If you receive the error message:
Error: The current transaction cannot be committed and cannot support operations that write to the log file.
Check the SQL server to make sure that it has not ran out of disk space.
The databases have 3 different Recovery Models (Full, Bulk-Logged & Simple). Setting the Recovery Model to Simple will use the least amount of disk space.
The following Microsoft KB article explains the differences in the Recovery Models: https://msdn.microsoft.com/en-us/library/ms189275.aspx
To change the Recovery Model open SQL Server Management Studio and right click on one of the Uluro databases. Next select the Properties menu item an navigate to the Options page. Finally select the Recovery Model of Simple and click OK.
