Table Prefixes...

I was wondering about the table prefix I have, it's not the defaults.

Will this cause problems if I simply change them in the sql? Or do I have to also find them in the pages and adjust them there somewhere as well.

If so, could you please advise which files will need to be modified.

Finally, I'm running 1.3.7, not 1.3.8... Please tell me that won't be an issue... ;)
