Reinstalling release candidate 2 will not fix the problem. The following should fix the problem:

Make sure evopedia is not running by first starting evopedia and then "clicking" on the exit button (door).

Next, open the x terminal and type:

rm .evopediarc

Then start evopedia. You need to select again the directory where you saved the dump.

You can check if it worked if you can choose from more than one map type in the dropdown list in the map view.

I hope it works.
