Hi. I recently upgraded to Ubuntu 12.04, and I can't seem to get Xmind running. I try any version I can get my hands on and I receive some variation on the following message:

I re-installed the program for Linux 64 bit - I was having trouble downloading it from their server before. This fixed it up. Still a little whacky, though: the logo screen XMIND comes up along with the usable program, and it stays there.
