PayPal Return to Merchant Hangs

Hey, I've searched for about an hour on various sites and this one and can't find anything that exactly matches my issue.

I have everything set up properly as far as products and email go. I tested a downloadable product using the Free method and it works great.

I want to implement it using the standard paypal form of payment. I tested this a few times and each time, I get to the paypal page and it processes the payment and when I click on "Return to Merchant" it hangs and displays nothing. I've tested it 6 times. 4 times it displayed nothing and 2 times it displayed the following.

Please help!

2013 Lost connection to MySQL server during query
in:
[select customers_email_format from zen_customers where customers_email_address= '*** REMOVED****']
2006 MySQL server has gone away
in:
[select count() as total from zen_sessions where sesskey = '** REMOVED****']

I installed a few templates, but have since reverted to the original.
