Registering file types

[DJFK]

First on XX5 and now on XD6, i get the message:

"This version of Xara (version) is currently not registered for.XAR files. Do you want to register it?"

Is there somewhere in Xara that i can register the file type, or could it be a Windows Registry error?

It is not that serious, but i would love to not see those lines when starting Xara.
