ARIS AArisLoader Class

Hey there,

I unfortunately forgot to close Aris Express before I installed the new patch. Now I get this message every time I try to start Aris Express:

"Unable to find the AArisLoader class. Please repair the settings in launcher.cfg and try again."

I have tried deleting all files related to Aris and reinstalling. Is there a way I can get this going again?

Many thanks,

Harish
