Help! The trial version of AE, won't load apps after downloading the CC .exe file - shows blank box

Help, I'm new to this!

I'm so excited to try AE, but after downloading the CC .exe file and clicking the "try trial" button - the CC box is blank with no apps.

1. I went through all the FAQ and System Requriements List.
2. I unchecked Pop-Ups, but I don't feel comfortable with turning off my Firewall.

My ASUS Computer:

• Windows 7 (3-4yrs old)
• RAM: 4.00GB
• Free Space: 139GB
• Pentium (R) Dual-Core CPU - T4300@2.10GHz
• 64-bit Operating System
• Intel Pentium

So, be honest - Is my computer unable to handle this? I would love to join the CC, and this is where I want to start.

I'm on a tight budget, but If my computer is too old, please give suggestions on buying a new computer - Brand, etc.

Thanks so much!
