I installed BF2 when my friend told me about PR, it did work, also after installing patch 1.5. When i installed PR 0.91 and i tried to start it up, a black screen appeared, as you it does when something starts up, but then it returns to Desktop. After i installed PR, BF2 doesn't work either. i reinstalled it and tried it again but it didnt make any difference. Help would be appreciated because this problem is frustrating...

(sorry for double posting but i thought i might be on the wrong page)

Maybe this?

BF2 not updated to v 1.41 before patching with v1.5
FULL update 1.41
followed by the
Final v1.5
Then install PR



Good luck
