Tried to convert my MultiStar Maximum 2500 to Digivave 7000 through FTLink3.01 (also tried FTLink 3.4), but always got "Connection Error", seems the connection can not be established between FTLink and Receiver COM1 port. I am sure the NULL modem cable works fine. I should greatly appreciate it if someone can help to point out what's wrong. Is the loader not compatible? If so, what is the correct loader should I use? Or something else? Thank you in advance
