CNA throws java error when trying to edit EtherChannels

[TroyDavis]

Couple months ago the FW on my Catalyst 3750x's were upgraded to 15.0.2 SE11.  I haven't had to edit my EtherChannels in years.  I've changed servers around and so need to edit and CNA throws the following Java error even though I can change anything and everything else on these two switches w/out any issue:

I did have CNA 6.3.2 and just upgraded to 6.3.3 and I get the same error.  Thoughts?

So I take it nobody has any suggestions as to why this isn't working or what I can do to get it functional?  I know, I know...CLI right?  I know diddly squat about cisco cmd line which is why I always used this w/out issue. 

If this won't work, what commands can I do to remove one connection out of the LACP group and into another existing LACP group?

[TroyDavis]

So the only thing I need assistance on is to move one port out of one existing Etherchannel group and into another Etherchannel group...

Etherchannel group 7 - move port 16 out

Etherchannel group 6 - move port 16 in

I can PuTTY into the switch no problems, I'm just confused as to the correct commands to move port 16 out/in...
