I'm having the same problem. I downloaded the Adobe Download Assistant and had no trouble downloading Photoshop cs6 but still get the Access Denied message (see below) when I try to download CS5.5. I have disabled the firewall and all the security on IE 10. Please help!
You don't have permission to access "http://trials2.adobe.com/AdobeProducts/STAM/CS5_5/win32/MasterCollecti on_CS5_5_LS1.exe?" on this server.
