Your screenshot showed a few files which are exactly the same as those in the Ultima Edition, as well as some other pirated versions. ISOs? Fine, a lot of us make our own to get around the CD check. But those specific ISOs? They are from Ultima Edition. Vgr recognized them and so did I. Not to mention, I'm fairly certain your error message is one that shows up when attempting to use Ultima Edition.
Lying to us and acting indignant isn't in your best interest. Even if we didn't have a rule about it, many mods and tweaks don't work right with non-official versions; there's all kinds of problems that have been added by stupid pirates who don't know what they're doing, so they changed a bunch of stuff for no reason before uploading it, and it makes it not work right with mods. Attempting to use anything but a legitimate copy of the game is just asking for something to go wrong.
If you wanna post proof that you have the PC version of the game (photo of CDs, preferably next to a sheet of paper with your username on it), we'll gladly provide support for your game... provided you stop with the insults and show some respect to site staff.
