I recently purchased Vampire: The Masquerade Bloodline, however when I start the game I get an error along the lines of: Available memory less than 15gb!!!

I hear its a problem with the old Source Engine working with 64x Win7, but I have no idea how to fix it.

Any help would be appreciated.

I remember having this problem to. I THINK you need to right click on the main exe and go to properties, go to the compatibility tab, and set it for Windows 7 (or maby it was XP)

There are a few solutions, but the best would probably be to install the http://www.patches-scrolls.de/vampire_bloodlines.php, which fixes a number of problems, among them, I hear, that one. I would also recommend just installing the basic version of the patch, not the plus version. Both because it's your first time playing (plus adds stuff), and because the plus version tends to botch my game and make it unplayable.
