this is really fucked.. here is one crack advice for 4.0:
*****
I made this crack as a thank you to this great community
only for the vault members, so please dont share elsewhere.
put it under c

rogramfiles and drag a shortcut to desktop or to
"C

ocuments and Settingsyour usernameStartmenuPrograms"
where you make a folder named xrumer4 or whatever.
as in previous versions you need a server installed, i use apache..
actually i use a packet named sokkit from
http://www.blackhatworld.com/blackhat-seo/black-hat-seo/www.sokkit.net. this contains
apache server, php, mysql, phpmyadmin and you can dl perl, ssl and mail
modules to it too. it comes with an installer so it's wery easy to set it up.
set up sokkit (or some other webserver packet) with the modules you need,
then go and edit your hostfile so it looks like this:
127.0.0.1 localhost
127.0.0.1 botmaster.ru
127.0.0.1
http://www.blackhatworld.com/blackhat-seo/black-hat-seo/www.botmaster.ru
127.0.0.1 botmaster.net
127.0.0.1 botmaster2.net
127.0.0.1
http://www.blackhatworld.com/blackhat-seo/black-hat-seo/www.botmaster2.net
127.0.0.1
http://www.blackhatworld.com/blackhat-seo/black-hat-seo/www.botmaster.net
127.0.0.1 216.195.49.207
127.0.0.1 toplib.ru
127.0.0.1
http://www.blackhatworld.com/blackhat-seo/black-hat-seo/www.toplib.ru
Open up the "botmaster.ru" folder in "xrumer4platinum", move contents of
www or folder www to proper location on your local webserver.
then go to (in sokkit) C:sokkitsite and edit (would be folder www on other servers)
"rem.php" open it in notepad and change this line "site: XRumer 3.0 + Hrefer 2.0"
to "site: XRumer 4.0 + Hrefer 2.0" and close it.
now you can open up xrumer (xpymep) it will make a hardware key and ask you for
the purchased key, just enter any number combination you like and it will say
"Thanks for activation" and close..
wait a few sec to its loaded out of your pc's memory and restart it, and it will
authorize. you will see it at the bottom of the program windows and in the log viewer.
if it says "Thanks for activation" when you opens it seccond time it was not loaded
out from memory but just click OK and wait a moment and start it again.
this happends because of its protection (and maybe buggy code) it takes a
lill time to unload it from memory.
When it comes to registering, activation, login, pass, test of xrumer_key and online
verification the program does a lot of tests and loopbacks on every function to check
if the value is correct or corrupted in some way. and besides this the program is packed
for further protection and it has some segments encoded in unicode.
The source code looks kinda buggy and looks like an improvement of V3.0, with
some references to it spread around.
your login and pass is:
Login: rich56
Pass : pi5dg
just like in the uncracked xrumer uploaded here some while ago.
Look in the help file for whats new in V4.0
Have a nice day

but.. as i use denver for server, don't know what modules to setup and what host file, and don't know if it has something with this problem: i made changes in www folder, but when i start xrumer, if i block it on firewall it is always giving the message thanks on activation. if i unblock then there is message for wrong login and password, and they exist in the option toolbar as in this crack tutorial.. something is not god done eather with my try or in the tutorial.. hard for making it working.. and i guess it is doing a good job.. and what is strange with tutorial is why to change in rem.php in denver the line xrumer3.0 in to xrumer4.0 when in the www folder in the main program the line is xrumer3.0..
