Brian, I'd say you haven't been asked to reformat your drive but I see you are doing the next best thing tomorrow by starting on a virgin PC.
When I went through this same scenario, it wasn't my PC, it really was a bug on the server on PTC's end. After that, the LC was hit and miss depending on the day, the temperature difference between my Internet connection and theirs, and if there was lighting and thunder between our locations. Seriously, I received maybe 1/2 of my full subscription service, but PTC was keen to cut it off at the end of my 1st year maintenance none the less. Every year I pay more and get less!
