Hi. I use ARIA player with a SLMkII with Presonus Studio One and Logic Pro 9 using a 2011 MacBook Pro with 2 GHz Intel Core i7, 16 GB ram running OS X 10.10.5. I have found that ARIA player has been causing Logic Pro 9 to crash and so I updated the software and now Logic Pro 9 seems to be stable. Studio One will not start up now and shows error messages that ARIA player and novation automap is causing it to crash. 

Please can any help or offer any advice as I am in the middle of the music project?

Many thanks in advance..
