Dear Sir/Madam I?셫 running DVMpro2010 on my PC and had a problem to open it after IT people connected a domain system in our company. Any setup confused the DVMpro2010 program so that I was forced to de- and reinstall it. After reinstalling I?셫 now asked for the Authorization Key because the previous one (first registration) is in use. I?셫 kindly asking for quick help because I need to work with the program regularly. Please find the register file attached. Thank you very much in advance! Kind regards Stefan Zwicker
