Cubase 5 crashes on working with quick controls

I have a problem. Cubase 5.5.3 crashes when I try to configure quick controls on current track. It cause something like “unexpected error” (i don’t know exactly how this error looks in english, my OS is for russian users) I use OS X 10.8.5 on Macbook pro i7. I can send text of the error, if it is needed.
Help me please!
