Hi, when i click "rebuild forum stat files " in Control Panel i see this error "was unable to unlink forum_thread_data_0000.cgi: Permission denied at C:/pubroot/platforum/cgi-bin/ubb_lib_files.cgi line 177"

177th line of ubb_lib_files.cgi is empty.

what this error means and what should I do to get over it

Reupload ubb_lib_files.cgi (make sure you transfer in ASCII mode) and check permissions (755.)

Also check the permission of forum_thread_data_0000.cgi (everything in that folder should be 777)
