I am new at this so please bear with me....what is a "Torrent" file? And why all the mirror files?... e.g. RSP, SSY, & XRPM? I have upgraded to build 146, I have downloaded all mods, most everything working fine, but here's my problem...In Mod Manager I get the message "Unable to install Mods". The Mods I can't install are IsR Corvette 1.0 Mod, Corvette 1.0 Mod, GT World Endurance Championship 1.0 and 1.1 is installed. (1.0 is in the Mod Manager...can't install it or get rid of it even tho 1.1 is installed.) Last but not least, Renault CLIO Cup 1.mido...cannot install it.
