Creative Cloud App just showing blank white box! Cannot install Photoshop

Question

I'm trying to install a Photoshop trial - have followed instructions to install the CC app. The icon appears on my desktop and a Creative Cloud folder appears in my Explorer folder but when I click on the CC app, all I see is a white box.
Occasionally, I have managed to get list of apps to show - but when I click on the "Try" button next to Photoshop, again it goes to a blank white box. Can't do anything! No spinning icon showing that something is loading - just blank white.
Very frustrating. Just want to download the trial so I can decide if I want to buy. Am on Windows 8 (64 bit). Have tried uninstalling and re-installing using a different browser (Firefox & Chrome) but still same result.
Please help!!
Thank you,

Hi again Jeff - I just read on a similar thread that another user had the same issue with blank CC app and realised the problem was her username having an ampersand "&"
I have an ampersand also in my username on the computer - do you think this might be affecting the issue?
She gave instructions for changing the username (although the link is for Win 7 and I'm using Win 8) - but I'm nervous about changing big system things like that. What happens to "permissions" on certain folders - am I likely to be locked out of making changes in certain folders?
Here is what she wrote on that thread:
If you have ampersand (&) or other non-alphabet characters in windows user folder name (Example: C:\Users\Bob & Mary), then Flash Builder will fail to install (happened to me), Creative Cloud will display white screen, and/or other miscellaneous problems.
I confirmed this to be true and works:
1) I had blank Creative Cloud window as shown in the first post.
2) I renamed the display username and window user folder name by doing the instructions here:

   (Example: Change from "Bob & Mary" to "Bob n Mary" - without the quotes)
3) After logging back in my newly renamed account, I opened Creative Cloud and login interface shows up! :-)
I would prefer not to do this if you have another suggestion? But just thought I'd mention this as well to see what you thought.
I have also since tried uninstally CC, deleting both the OOBE folder and the AAMUpdater folder, then re-installing CC again... same result. I always get to the list of Apps fine but the minute I click on the "Try" button next to Photoshop, the whole App window goes to a blank white screen and freezes.
Thank you.
