Glad that things have improved!
Just one more thing. Scrapebox will use the connection you provide to submit the comments you provide to a blog list you provide. If one thing from this chain s broken, it will simply fail.
Start from the beginning and figure out what works better for you!I know that what i am saying is really general but it is simply how it works.
Checklist
-Check your connection including proxies. Fix Timeout out Setting, Multiple Connections Connections ( some providers including mine are not that good), Proxies
-Check names,comments etc ,
-Check the blog list. Comments closed, Captcha, Moderated, Not found blogs, Unknown Platforms etc.
if you do that you will be fine.
If you are using super fast and reliable ISP and you are using the fast poster, things are much more easier. But for the slow poster, if you have not cleaned your list and you want to complete a 3000-4000 raw blog list, it will take forever. So in my opinion its better to trim your lists and have lower timeouts etc than be bored to do that and then complain for scrapebox.
