I don't know how this happened, I imagine that after programming someone upgraded the FW. Would it be possible to downgrade the FW without losing the program that is running?

Just create a new projekt - without configured CPU! Online -> Upload as new station hardware + software. If you get an error message via this method, please post a screenshot. regards sancruz
