Car doesn't start after ms43 tuning..

(BMW 325Ci Convertible from 2001)

I followed the tutorial from bavarian and beyond, all went well, i flashed with the old EWS Delete from daniel for the B25 engine with jmgarageflasher but when i started the car it went into EML mode, so i went back to the backup of my original DME and the car started as it should.

Then i found the new DME Files from ms43wiki for software version 69, flashed it with jmgarageflasher and then the car just cranked over without starting, so i tried to go back to my backup file again but it wont even start with that flash anymore..

Anyone got an idea of whats wrong?

did you correct checksums?
flash your original file back and then flash v69 with MS4x flasher.
