Shortcut in the start menu and prbf2 protocol handler are broken because of PRWW2

[qwerty,]

I've installed PRWW2 some days ago then tried to start PRBF2. It said it could not find the mod directory. After some "research" I've determined that shortcut has been modified. Then I have modified it back so now the directory in which the launcher starts is "C:\Program Files (x86)\Project Reality\Project Reality BF2\mods\pr\bin". Protocol handler uses its own shortcut or something else and I can't join any server using PRSPY, the same error 8 appears. How can I fix this?
