Diablo anounced a problem when updating to R19 with no start issues on the 07 level vehicles and has pulled the r19 release off its WEB site.. So if you have not updated your predator DO NOT they will release R20 ASAP to relsove this issue...
Acording to Diablo the 06 should be okay,,but no matter what I would update your predator to the new release when they post it on there site to advoid any possible issues if you already have R19 loaded..
