Sorry to refuse this, but you paid for license of using the software we offer. You did not pay for our code, neither you paid for us to tell you where and how to hack our code. This is our know-how and that is what we make business on.
Our license is loose enough to allow you to do changes for you own purposes - that is fine, unless you distribute it further. But we never promised anywhere in our license agreement, that we will assist you with those (for free). And we will not. Guess you would not give us the stuff you are selling for free either. Sorry.
You are asking an EXTRA service from us, we are asking you to pay for it. I guess that is fair enough.
P.S.: Also, please note the user signatures in this forum were not ment to create back-links to your websites. That is why we have removed them.
