Error showing and I don't know what caused it.

Hi all

Very new with Xara extreme pro 5. I have created an 8 page website that is still in the process of being completed.

I have been saving it as a .xar file. As I am still in the process of completing it.

Now when I go to reload it back into Xara it stops during the adding colors to the document of the reloading. and puts up this error(see pic below as well)

Internal program error 1765.k.no.nt

Once I click OK or click the close button (X) the site loads into Xara.

I have gone through the manuals and videos as well as did a search here to find out if I am doing something wrong.

Can you give me some advice I would like to launch my site in the next day or so.

Thank you
