I purchased a Fastcard digital version of Cuphead

I purchased a Fastcard digital version of Cuphead years ago I recently have had some problems with my console which led me to factory reset my Xbox One S. I have been able to reinstall the game but it won't launch keeps asking me to insert disk ect. But I never needed a hard copy of the game because it was a Fastcard digital version of the game what do I do to fix this
