Reached email limit?

I'm trying to email myself a copy of the form I just completed and I'm getting "oops, you've reached your limit". I didn't know there was a limit regarding emails?  I've checked my limits and they're all still within range.  Help????

There is a hourly limit on the emails you send. If you try it now it should be resolved.

By the way, the limit is much higher on paid accounts. ;) 

The only reason I reached the limit is because I've been testing - thank you!
