Unable to mmap new descriptor file

Mar 29 23:23:54:062 [Warning] Unable to mmap new descriptor file at 'C:\Documents and Settings\Ils Haxor\Application Data\tor/cached-routers'. This warning keeps popping up every time I run Tor. No matter what version I have used, both stable and the newest one, this keeps occurring. I am pretty sure this is my only problem, but I haven't even been able to use Tor yet. Anyone know what to do?
