Illustrator CS6 in Yosemite hangs on open

Question

Recently I'm experiencing this annoying situation which I cannot solve on my own.
Situation: MacBook Pro Early 2011 model, problem free so far. Running Yosemite for a while now, latest version. Daily user of Adobe CS6 package. (no CC)
In Adobe Illustrator CS6, when clicking "Open" (or command O), the spinning beachball occurs leaving me no other option than to force quit the program. I cannot open any file in Illustrator. However, double clicking a file in the Finder does work, must have something to do with the dialog box?
Tried so far:
— Safe Boot
— Deleting P-ram
— Deleted and reinstalled Ilustrator
— Java updates
— disabled Dropbox
— disabled Default Folder X
— Removed FontExplorer X Plugin
.. no luck so far. Can anybody advice me on how to solve this?
Thanks!

Ok...Finally got my iMac back. I realized there was some glitch with my system (only able to open illustrator from a new user account). I chose to move over to the new user. After many hours of creconfiguring my prefs and such it is back. Runs mean and clean again. I did discover an almost horror when my photos library and images was not there, not working. I used a third party "Anytrans". I was able to get all my library images back form my iPad. Whew!
Thank you all for your help and encouragement. I am back and running well again. Needless to say have learned alot.
