Honeywell Vista 15p Download Problems

[Rainbow Dash 7x]

Just thoght posting here would help me, so i have a Honeywell Vista 15P alarm panel with 2 keypads and the panel works ok its just i can't download to it. I open the Compass downloader and go to communications, start it and the modem picks up, panel answers and it starts making tones. Seems to work just fine but then the modem just hangs up on the panel. Not sure what is causing this,things i have tried listed below.

different telephone power supplies
restarting computer
restarting panel
defaulting panel
re-installing the Compass software
different phone cord
different modem
re doing all the programming in compass software

Help would be greatly appreciated.
