I am having a similar problem.  I have the correct COM port selected.  I was able to update the OS from the Controller>Operating System menu but cannot download my project.  When I go to Controller>M90 OPLC Settings to verify, I get a "Communications could not be established..." error.  I am using a USB-to-RS232 adapter (COM8) and Windows 7.
