Xthreads problem

[t_virus]

I run a gaming forum and i installed a video gallery on it (thanx for this wonderful plugin, it worked like charm)

But recently, an attack occured on the server. The old forum files were removed but i had the mysql database. So i installed a fresh copy of mybb 1.6.5 and merged it with the old forum database.
Then i installed xthreads and re-created my templates, custom thread fields,  changed forum settings etc....but my video gallery forum show up as normal (the xthread templates are not being shown)

Also, i notice a strage page with bunch of PHP warning and other things when i change things on forum. The page says something about xthread_evalcache.php but it stays for a few seconds and goes away

I tried reactivating the plugin but still no help.
