Multiecuscan

Hello, I have just probably ruined my Alfa with MultiEcuScan. I have tried to run DPF regeneration, but instead of that I have clicked on "Replacement of control unit and injectors" option. It said something like "failed to proceed", but after that my cruise control has stopped to work. If I turn the ignition ON and switch the cruise control ON, the light on the dashboard won´t come on. If I open MultiEcuScan and connect to engine ECU, then on the tab "Parameters" there is no signal from cruise control switch. In the tab "Acurators" it is impossible to activate "Cruise control light" because it says "Failed to proceed". Do you please somebody have idea how to make it work again? Thank you very much.
