Default Tuneing issues

Did anyone have this problem while tuning there car from RR-racing (pic related)
i already had the tune installed but had some alternator trouble a few's days back, after i changed it the car started running a little rough on start up so i though reinstalling the tune can help
but then i got this message (exceeded number of write attempts on this file) shortly after that my abs, anti-collision and lane departure lights on my dash comes on and now its not going away

Did you remove the tune before reapplying?
Contact the provider for guidance?

yeah as reluctant as he sound he sent me a tune file that fix the car rough idling and slugish shifting when back to stock. I fixed the codes threw the dealership It just need a zero point calibration but every thing is good now, I put the new 7400rpm tune on my car runs like a champ 😎

Oh and tell Rafi it wasn't a waste of time 😏
