Collectible Card Game Headquarters

So, all of a sudden Xmage wont start anymore. As soon as i click on start client it does this :

As someone who has absolutely NO idea about java whatsoever i cant understand what its trying to tell me. Ive tried reinstalling xmage as well as java, restarting the computer multiple times. I am out of ideas.

I would appreciate some help on how to fix it.

Try installing xmage in its own separate folder near the root of the drive. At the very least do not have it installed within your user profile folders (desktop/documents/etc). For instance, I have mine installed under c:\games\xmage on one computer, and c:\xmage on another.

Also try uninstalling your current version(s) of Java and redownloading the latest version of it. Finally, you can delete the file it points to "<your-path>/xmage/mage-client/db/cards.h2.mv.db" as it will be re-created on next run of XMage.

thank you very much, i had already reinstalled java a few times, since i was trying to fix that weird graphics bug i keep having. However, i deleted to file it pointed to and IT WORKS. Great help, thank you very much.
