Hi, new here, but old to mtg. ATM I'm using a Microsoft surface tablet that I have urzas gatherer installed on to connect to deckbox. UG makes the CSV file export nicely but then when try to import to Deckbox it simply won't do anything. Any ideas? The fix is probably to not use this tablet but maybe something is known... Thanks!

I'd suggest getting in touch with the author of the Urza's gatherer application, and let him know of the file you are trying to import.
