SR 2.1 disconnects Loser5 from the "protection" afforded to it by Interlok. That's all. (I.e. CL recompliled without including call to Interlok - already installed by Loser 5 from teh CD.) So if you do nothing else Interlok is still running. CL claimed they didn't have it set to market-harvest data beyond the registration stuff, and PACE (author of this game-protection software) says they don't have it calling home. But it is capable of all that and then some, and it's still present and running, using up memory and cycles. And whatever it does/doesn't do, it sure ain't going to improve the smooth operation of your system! The install/de-install still doesn't remove everything, but it removes the drivers, so the puppy is not able to run or consume memory anymore. To remove everything, you'll need a Registry cleaning application - Interlok is set to prevent removal of it's entries by hand. You could find install on PACE's site, for people who need to upgrade Interlok, and CL posted a like in the Beta forum if you want to search - just after the 2.1 release. (Still sucks to have to do a full install from a company like PACE - which might do ANYTHING - to remove GARBAGE put on your system by CL, IMHO - but that's how it is... I did it, and could see nothing untoward going on - but I did stop all network access while running it ;-) But before you remove it, you'll need to know that no prior application of yours was using it. If you're wrong, a) that other app won't run, and b) you'll have to go through a full install, re-register / prove you didn't dteal it ritual. BTW, anyone know how to remove Macrovision's similar tool that came as a "free gift" from Intuit?
