Hi folks, I've been running P3D v2.5 with UT2 for the last 18 months or so with no issues. I purchased FSUIPC4 last Friday, and after the install, UT2 now throws a registration error ( "Please register this product before you try to use it!"). The FSUIPC install looks to be straight forward and I can't figure out what has caused, or why, UT2 is now giving me problems. Anyone ever encounter issues when trying to run these together? Thanks!
