Cannot open offline model- Message 'Value cannot be null Parameter name: value'
i had a problem recently .
The problem started after i leave a wifi area on 10 min.
After i had get back i have try anything: changing on online mode, saving model online, saving model as bpm - nothing works. The model was in the list of cloud models, but when i try to open the message appeared: "Cannot open offline model- Message 'Value cannot be null Parameter name: value'"
Lucky i can fixed this when open model from web-interface and pressing "edit in bizagi"
