Web Desinger 6 will not open .web file

[Waltn]

Today when I try to open an existing .web file using file-Open I get two error messages.

The first- see attached open.jpg and clicking on continue I get the second error message - see attached error.jpg

Clicking on any button shown on the error.jpg caused the Web Designer program to close completly

I have sent the error report to Xara.

I also have Web Designer 5 on the same computer and it works without any problems

Any ideas?
