Error like this. What can i do? :roll: [/img]

You have to (re)install your missing/corrupted mfc42.dll file:
http://www.dll-files.com/dllindex/dll-files.shtml?mfc42
Put the (extracted) file in c:\windows\system32 (for windows xp)

It can`t help me. Any ideas?

Maybe you could try to delete your BSPlayer directory,
"c:\Program Files\BSPlayer"
And delete the file "c:\windows\system32\MFC42.DLL"
After that, re-install BSPlayer.
The missing file MFC42.DLL should be installed by BSPlayer.
If not, download it from dll-files.com
By the way, if you have Windows 98,
you should use c:\windows\system (without 32).

Thx, seems like it helps. :D
