halion 5 is unstable / unusable

Hello, I have Halion 5 and it’s completely unstable on my Mac book Pro, I have tried using it in Cubase 8 Pro, and Logic Pro X with the exact same results. 4 instances of the plugin and my entire system craps out. Instrument load time is also very bad. My computer specs. If anyone has any advice or help please let me know thank you very much.

Computer Specs:
MacBook Pro (13-inch, Early 2011)
2.7 GHz Intel Core i7
16 GB 1333 MHz DDR3
128GB SSD Drive (60 GB free)
OS X 10.10.2
