Oh, I had a vista operating system for awhile. You right click the exe file for RMXP, and select "run as administrator". That cleared the problem for me. I don't have Vista anymore, so I can't give exact directions for the following, but if you right click the RMXP exe, there's some settings somewhere that you can tell it to always run this program as an administrator (I did it before, but maybe that was done via the RMXP shortcut. If someone actually has RMXP on vista, they'd be a better guide on how to do that x_x)
