Mathcad 15 student version license issue...

Hi!

I recently just re-installed Mathcad 15 (student version/license) on my Windows 8.1 machine. Every time I start Mathcad 15 I get the dialog saying something to the effect that a license could not be found. So I go through the process every time of choosing to reaquire my licensce via internet from PTC...

Does anyone know of a fix for this aggravating issue?

Thanks,

Pat
