I am running classic client on Windows 7. Normally I load my first client via UOA, and my second client via the classic client "patch client". When I try and run this now I get the patch screen with a message that says "patch error" and an additional dialogue box that says "patch error - the program was unable to complete the patch operation. Please try again later". I should note that I can load a second client via launching the client directly, but I have never needed to do this before, under normal circumstances that is.
