Hi Coriolis,
Sorry you're having problems. Suggest you go to the homepage (www.ud.com), go to, I think its contact us option, and there is techincal help form to fill in.
A few of the other forums I visit have started teams to increase their computing time. Would it be worth starting one for Engineers. I wonder how many downloaded this programme and are helping. I've got almost 4 days of CPU use. The record for one team is over "18 years" Give me your thoughts and I'll form a team if you thinks its worth it.
T.I.M.
