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.

I'm not sure the exact steps, but the issue was resolved. I had shared the model with someone and was able to access it online via the link. Once I was back in via my browser, I was able to close it and come back in using the modeler application without any errors.
