sorry it didn't work out for you. i took a look at the open ticket you have with support and there, you don't mention crashes at all. also, you last reply was something along the lines of "That seems to do the trick. There are still some weird hiccups going on but at least I’m now able to play the keys with no sustained notes at all."
is there a second ticket i should look at?
No, it was my only ticket.
And yes, I thought it worked but it only did so for a while and then it started crashing all the time and I didn't bother making another ticket since it seems to be a common problem from what I've read in a lot of threads, not just here but in various forums.
