Those fields are already in field manager, but not in the profile tab. Does that matter?

Nope

When I removed "forumposts" it worked. It didn't seem to like that field.

Now, it seems like it will stop every 27 or so imports.

I am running the site on a laptop, and don't have any email clients installed, so each import throws an error that says that it couldn't initiate the email function.

Does the plugin stop importing after a certain number of errors? If this is the case, then I'm good. When I move the site to production, I will test the email function before I run the import and I should be fine.

I didn't really need forumpost counts anyway.

So if I can just confirm the error handling, I'd appreciate it.

the script times out becuase of the email issues caused by runningin xampp. you should have no problems when you go live. I cannot turnoff the email functions of cb and joomla. I wold check yur tables for consistency with cb/tools
