@JTRTech he had his set to Text Demo Mode. Unfortunately @cowvin there will be no way to migrate that. You will need to rebuild it. I recommend not using CE as its much slower and limited compared to SQL. You should install the localDB version or install SQL Express 2014 instructions are located here:
To explain demo mode, It uses a single text file to temporarily store some data but it will NOT work for very long and it is NOT a database.
If you choose to go the SQL Express 2014 route you will find its much more flexible and gives you greater control and performance.
