Looks like they finally did fix this issue, though some of us were smart and might just happen to have the old installers that should still work with this trick... Not that I'm endorsing software piracy or anything, but as stated, it's not illegal unless you distribute the games without buying it...
EDIT: I just checked with my copy of VX, and yeah, the trick still works. Looks like they didn't find a way to have the activation server check to see if it can determine what "version" of software you're installing (old DRM vs. Non). I would think the smart thing to do would be to have a trigger that detects if your trying to install the old DRM version, force the user to download and install the newest version, thereby bypassing the little trick itself. I mean, really, how hard could that be?
