Question on MarketPress Fatal Error

Been getting fatal errors on marketpress and I think I know why, but might be a little stuck.

I see that Pretty Permalinks and rewrites (mod_rewrite) needs to be enabled.

Pretty Permalinks are done, but with rewrites I see that apache needs to be enabled.

My server uses suPHP and run PHP in CGI mode.

Would that be the problem I'm having?

If so how do I get around that using marketpress (if possible)?
