I have been having some trouble downloading mods from the internet. The most used mod website i use is filefront, but usually when i download a mod there a some files that my computer cannot read, therefor the mod wont work. the files that my computer cant read are uti, utp, txi, mdx and mdl files. there has to be someway to open these files because it seems like im the only one wit this problem. also my computer is running windows 7 . Thanks, ill appreciate any help .
