Moving Libraries to SSD

I recently moved a few libraries to an external SSD, Logic, Native Instruments, Superior Drummer 3, and Steam. After redirecting they all seemed to work fine. In Logic however I can't load any software synths other than Drum Machine Designer. In existing projects the soft synths are present and work fine but I can't create any new instances. I tried to relocate sound library and shut down my Mac and still no luck. All programs work fine outside of Logic but I can't add any of them to a project. Any ideas?
