RED is ORANGE in PSCS4 and LIGHTROOM 2.1

Since upgrading to PSCS4 and LR2, RED has become orange in my Adobe apps. R=255, G=0, B=0 is pure orange. I calibrate my monitor regularly (Gretagmacbeth) and red is "red" in other programs, websites, desktop icons, etc. I have PS color settings: ProPhoto RGB (same as lightroom2), Gray Gamma 2.2, Dot gain 20% which were settings I used in CS3. Intel Mac Pro G5, ATI Radeon X1900XT and the driver is current. A red leaf in PS looks orange but PRINTS red (I also use Epson printer profiles). Since upgrading, my problem has migrated backwards... red is also orange in PSCS3 and Illustrator CS3. Suggestions greatly appreciated!

Bad monitor profile

That is why I suggested logging in as a new user, he is probably not going to believe you until he does log in as a new user. When doing so the Monitor Profile does not follow to the new user.
