WebPlus X4: What has gone wrong?

Hi

I just created a Website from a previously created WPX Template, which I saved as a WPP.

But when I tried to find it to do a modification it was nowhere to be found.

The same thing happened the previous week on another Website but it was getting late and I thought I'd forgotton to save it.

Then after going through every possible thing that I could think of, I found my Website had been saved as an MS DOS Application. (not even sure what that is)

Does anyone know what could have gone wrong? or even had the same problem.
