XFileSharing Free - Installation Question

Hopefully, someone can help me!
I have installed XFileSharing Free and the script executed without aborting? I am able to upload files and records are added to mysql.db. Something must not be set right, because during it's execution, some of the screens and status pages are reporting 404 errors. As I said the files are uploaded, I can go in and see them and see the records added to the sql.db. I never get the screens showing the dirs with the files or how to download them.
I think it may be in the mod-rewrites. I have checked with my hosting service and we can not find the issue!

Any guidance or help would be appreciated.

Thanks in advance for your help and assistance!
