Maschine Plus wont update (Update loop)

Hello,

i tried to update maschine+ to the newest update. It updated and started, then i tried to load in a instrument while downloading the new fx and then it shut down.

Now everytime i try to start maschine+ in standalone modus m+ tells me "There is an update", i can update, shutdown or restart maschine, when i press update "Update completed" comes, i restart/shutdown and it happens again.

I already tried the instructions on the post "Tips: What to do if Maschine Plus is stuck on startup screen", when i put the "system-reset-v2.nut" to the SD Card maschine plus tells me something like "system-reset-v2.nut is not a valid update file, please contact support".

How can i fix this? Please help i have a live gig in 2 months and i have to practise ,-,
