Error validating file

[Toms Black SRT8]

I have a 2006 Chrysler 300 SRT8 . I have a U7135 Predator . My software revision is v.9r23 . I've attempted several times to modify the parameters ( fan settings , shift points , rev limilter etc...) . It keeps coming back as "error validating file" . From what I've found on your forum is that this revision doesn't work well with the '06 cars . They say the 9r12 is the one that will correct this problem . Mikel from Diablosport also states "9r12 is all you'll ever need for 05-08 vehicles " . Upon further investigating , heres what I found : Release 9r12 (current w/o 09 support)(Fix for modify parameters menu running very slow) NEW PRODUCTION TOOLS CANNOT BE DOWNGRADED TO OLDER REVISIONS. Attempting to do so will keep the tool from properly booting up . This is what I've found here on your forum . I want to beable to make adjustments as I make improvements to the car but I am a little skeptical until you guys say it's ok . I'm hoping my Predator is old enough to be downgraded to the older revision . My Predator serial number is d003fa6 and it was born on 03/02/2010 11345 . I hope this is all the info you'll need . Let me know and thanks for your help . Tom

Put on 9r30. That should solve the problem. If it took 9r23 it'll also take 9r30. You have one of the newer tools.
