Any help or suggestions greatly appreciated. Well, it happened to me (twice) and fortunately in both cases we ware able to bring one of the customer's maintenance guys who didn't go fishing. They ware able to bring their laptop and help me finish the job. In my case it happened with GT Works and I'm still so mad about it. Just call Mitsubishi, they are usually easy to communicate with. Once i couldn't get anyone on the phone because it was holiday in USA (working day here in Canada). They also don't have 24/7 line to handle this and you get hosed if this happens on a weekend. Even if they did, working on site often means no reliable phone access. For example on weekend hardly anyone is in the office so no land lines, cell phone coverage is not good inside plant, and once you leave plant and door shuts, you are out for good or have no way to power the phone which drains battery very fast when signal is weak etc. (this is quite common for plants in rural areas). Cannot run defragmenter anymore, must use floppy drive to move licence every time. This however at least allows me to defrag but it's real pain to backup and restore licence every time like this. I don't know if killing licence and getting kill number that could be used as licence on fresh install will work if application itself is corrupted by any means (bad HDD sector, infected by malware or else).
