i think you use a hack of ***** thats why it happen. try to look your version.ini if there is no written there your cf is crash just like what happen to me about a 2 months ago. the solution is first try to get a copy of version.ini copy it to your version.ini then try to run cf. if the problem is still the same then reinstall the CF.
if still got a problem which i did to my pc is run a restore to your system....thats the solution i did..... i hoped i helped...
