Good news everyone!
We’ve just got a word from Sony that existing problems with game launch failing with various error messages will be fixed in the next Vita’s firmware update, 2.00.
If not fixed on its own by update, trying Vita restore should help.
It’s confirmed that the problem exists in firmware 1.80 and 1.81 and is fixed in firmware 2.00. To recover from the situation, you can use the ”Restore the PS Vita System” option from the Settings menu.
Hope you’ll be able to return to our game once the update 2.00 is up on PSN.
