The issue should be solved in the "dev" branch, with the correct connection string and and auto increment of the value. If you have some time to pull the last commits on that one, build and try, that would be great to confirm it works...
If you want I can delete the database and start from scratch to see if it ends up growing to the same size.
Eventhough the database is this big, everything works fine, and it finaly stopped growing at 1.2GB, now if I have MP2 server running the database size remains the same.
