I'm a former Xara Extreme user and have just purchased and installed P&GD. When I try to open a XAR file created in Xara Extreme, I get a message: "This file may not be suitable for this filter- are you sure you want to open this file?" When I select Yes, I get the message: "An error was detected in the document file. The import has been aborted." How do I open the files I created in Xara Extreme in P&GD?
