Can you try with 4.1.29?

Seems to be working now… but I cant login unless I quit the program and start it again… strange, and that seemed do happend also in v4.1.28…

I will try one more time!!!

G.

PS, I made it to training mode, but had to enter 1234 as pin, and no info was there, but in V4.1.28 this did not happen… and you have to completely leave program in order to re log in…

what does training mode do exactly in sql?

Thanks!!!

did you configured database name on backup module?

uuuuuuuuuuuuuuuuuuuuuuuuuu
YES

should I leave it blank??

PS As allways, you are the man!!! leaving it empty solved all the problems!!!

THANKS!!!

Haha sorry… Yes you should leave it blank :slight_smile: Maybe I should complately remove this setting since it is useful for very specific cases.

I think @Isaac’s problem was the same thing. I’ll handle it better on next update.
