Project Reality SP doesn't start!

[PatrickLA_CA]

Hi everyone!
After I have downloaded PR core and levels from the main download site, i have downloaded PRSP core and levels and installed them in this order:
1.PR core
2.PR levels
3.PRSP core
4.PRSP levels
And when I try to start it from the shortcut on the desktop or from BF2, a black screen appears and only the pointer shows up and then crushes to desktop!
Maybe because PR core and levels are 0.86 and PRSP core and levels are 0.85!
When i was downloading it there was no choice only those files!
Multiplayer works fine but not singleplayer!
My OS is Windows 7 32 bit but I've tried it on Windows Vista 32 bit and had the same thing!

The PRSP 0.85 files dont work with the 0.86 PRMP release.

No it's not PRMP n0.86 but 0.856!
