Hello, I recently used pokegen to create a few pokemon. After picking them up from the GTS, I went to do a wifi free battle on Pokemon Black. I make it through the connection process until the "Which mode will you challenge?" screen. I select Free, and it loads for about 5 seconds and says 'communication error...'. I released my made pokemon, and I still cannot log on. This has never happened until now. Any ideas?
