MaxBounty link will not shorten?

I have tried tiny . cc, tinyurl, bit.ly, and goo.gl.

None of them will cloak the link MaxBounty gave me.

Contextual link:
http://www.mb103.com/lnk.asp?o=8702&c=918271&a=87476&l=7414

Is this not the right link?

It shows up in their banner code, so I assume it is.

<a href="http://www.mb103.com/lnk.asp?o=8702&c=92348&a=87476&l=7414">
<IMG SRC="http://www.mb103.com/getimage.asp?a=87476&m=3697&o=8702&i=92348.dat" width=300 height=250 border=0>
</a>
...............

I need the link cloaked because it is going into a contextual ad that displays the link below the text. (its a 7Search ad) see below

When I cut and paste that code into my browser it goes to this URL
http://searchschools.com/short_form/index.php?pub_id=maxbounty_ss_shortform&sub_id=87476

However, if MaxBounty tells me that the above URL is the wrong URL to use.
(I contacted them asking why clicks from 7Search were not being recorded, they told me it was the wrong url at that time)
