Cannot open offline model- Message 'Value cannot be null Parameter name: value'
After bringing my computer back from sleep mode, I was prompted to either take my model offline or lose changes. I chose to take the model offline, but the dialog remained active and nothing happened. I tried several times and finally restarted. Now the model shows offline but gives me an error message when I try to open it "Value cannot be null Parameter name: value" Then another dialog opens "Specified cast is not valid", then a blank model.
How do I get my model back?
Using version 3.0.1.011 and trial version of Collaboration Services.
