Groov Configure Devices & Tags not working

We upgraded groov to the R2.1a with build date 3/6/2014 12:49 pm.
Since then we are unable to add opto 22 controller (tag import) into groov.
When I click on import the progress indicator come on and stay there for hours.
I’ve tried most popular browsers (IE, Chrome, Firefox, and Safari)

our settings are
snap pac R1 Controller firmware R9.3c
groov R2.1a build date 3/6/2014 12:49 pm.

Please help!

R2.1a is NOT the latest-and-greatest version. I recommend you get the latest. Sounds like you might be running into this issue (KB83710), which was corrected in R2.1c, where the port number to your controller gets set to 1 (vs. the usual 22001).
