Feral Heart

I recently downloaded a new map off the map forum, listed as the "Common Lands", or something of the sort. Anyways, entering the portal with my main OC, the game crashed, even after multiple attempts, including deleting and re-downloading the map itself. That being said, I can no longer access my character, since they only appear in the last map they were played in. Am i downloading the maps wrong? What can be done to gain access of my character again, rather than making him from scratch?
