After Effects CC still can't launch on Mavericks

Question

This seems to be a common issue but mine looks a bit different
Probably because of my lack of experience in mac or Adobe products!!!
Ok, my problem started from a window popped up saying "Install CUDA 5.0 or later and restart computer" or something like that when I first opened After Effects CC.
So I googled and found the NVDIA website and downloaded the CUDA 5.0, yep, I changed my security preference on mac to allow apps to be downloaded from unidentified developers, and then completed installation, easy! ...I thought.
After restarting the computer I re-opened AE, it kinda loads with this fancy purple 3D intro image, but this time it opened with nothing but the "****" noise (the error noise?).
All I see is the grey frameworks with "Render Queue" tab...no welcome screen, no tools, no "Install CUDA..." screen either.
The buttons on the top (File, Edit, Composition, Layer etc...) are clickable but the contents of each button are in light grey apart from the "Help".
I tried updating, uninstalling and reinstalling of AE, shutting down and restarting of computer, but no luck.
Does anyone has/had the same issue?? I just don't know what to do next
I apologize for the long story and would be much much appreciated if someone could help
What you can see on this screen shot is all I got lol.
My mac is OS X 10.9.2 and trying to use AE CC by the way

Thank you so very much for your advice!! I'm sorry for the late response.
(It didn't let me login yesterday so I couldn't reply to you immediately)
Based on your advice I was able to find the solution:
Re: After Effects CS6 full program won't open - only render engine
Finally I was able to find the main After Effects in my application file and it works perfectly - YAY!!
Thank you again for helping a crazy beginner like me
