Mappoint 2006 Trial expires immediately on installation

I have loaded a Mappoint 2006 trial on three PCs to explore data sharing, works fine on two PCs, counts down the remaining trial days.

On the other PC it has said the "Trial expired" from the start.

Googling indicates others have the same problem, but no answer

Any ideas ( surely I don't need multiple Trial CDs..)

Thanks

Hi Paul,

Multiple trial CD's would not help.

This happens I think because the software is thinking the trial was installed once before (even though it may not have been). Is there a number on the trial sleeve for tech support?
