Garageband Crash When Opening Editor/Midi

Hi everyone,

I recently installed the "Impact_Apple_Integration_OSX_1.0.5" on my Macbook Pro ( Mid 2012,El Capitan) to use the Nektar LX49 with Garageband.

Ever since the installation my Garageband keeps crashing every time I try to edit a midi file or try to open the editor.

The error type says:

Exception Type: EXCBADACCESS (SIGSEGV)

Exception Codes: KERNINVALIDADDRESS at 0x0000000000000030

Exception Note: EXCCORPSENOTIFY

What can I do to solve this problem?

Thanks,

Jakob Tollerian
