On Windows 2000 system, if I create a new forum, and attempt to make a post (or infact, if I attempt to post to ANY forum that currently has 0 posts), I get the following error message:

No such file or directory opening c:/inetpub/wwwroot/ubb/cache-2LUACNUM/search_index/forumindex14.cgi (called by c:/inetpub/wwwroot/cgi-bin/ubbcgi/ubb_lib_posting.cgi, 1019) at c:/inetpub/wwwroot/cgi-bin/ubbcgi/ubb_lib_files.cgi line 541.

Is it possible to fix a corrupt cache? I've tried using rebuild forum stats and clear cache, but I still get the problem.

This started on 6.05, and is still occuring on 6.10 beta 1.2.

Any ideas?
