Migrating to Jigoshop 2: Order Migration Error

I am in the process of migrating to Jigoshop 2. I’ve gotten so far as to migrate the orders, but I’m getting an error. It says Wystapil blad komunikacji prosze przeladowac strone i koontyneowac proces. I have tried refreshing the page and trying to migrate again and again, as well as logging off and logging back in and trying again. I’m doing the migration on a dev version of my site, so I can work out any kinks without effecting the live site. Please help! Thank you!
