Hi there,

Your site is actually listed on our piracy tracker as having an illegal version of AJAX Threads, DragonByte SEO, Advanced Registration, Advanced Post Thanks / Like, Advanced User Tagging and vB Optimise - we checked manually and there are indeed unlicensed Pro files for these products on your server.

For obvious reasons we are unable to support people using illegal versions of our software. If you do not respect our work enough to pay for it, then at least respect your own time and ours enough that you do not try to waste it by asking for support for your illegal copies of the software.

Regards,

the problem is not my website, I do not intend to ask for help in this. I just wanted to give my friend a favor, but if they will not support, no problem. I remain and tell my friend to spend good money to legalize their products. Thank you very much anyway.
