Need Mod Rewrite / Reg Ex Help ASAP

[Dravyk]

I have a site that already has in a mod_rewrite to turn those long, screwy dynamic strings into short, Search Engine Friendly strings. Problem is, the one I have messes up 10% of the job. It wasn't done completely correctly and there's no support, help or revisions where I got it.

At the moment some archives on the site cannot be accessed because the Reg Ex for that section was apparently done incorrectly in the file that came with it.

Need some help here, free or pay, to be able to have myself, visitors and search engines get into the archives by redoing the erroneous lines correctly.

Need this done quickly as possible! Please hit me up here or by email at dravyk at dirtygloves dot com Thanks!
