Urza is failing to boot up. I get the Orange screen with no moving icons and then just seems to time out. Running it on Windows 10 Ver 10.0.9.0

Hung up my cards a few years ago, but was using your Msoft app to track all my decks and cards. Just before I walked away from MTG for a short hiatus, I moved your app to an external harddrive. After I did this, it "broke". The orange splash screen pops up with the curser and then crashes. Now I am looking to fire it up again and wonder what you recommend to get it working again. I assume uninstall and reinstall? I had been doing regular backups in both of the available formats you were offering at the time, so I hope to be good on that front. thanks! S.
