I purchased this game and tried to download but everytime I select the download option, my screen just blinks and nothing happens. I downloaded the file suggested by the support steps but still no success. Can someone please let me know what else I can try? I also lowered the security in my browser.

I am currenty using Internet Explorer in a Windows 7 computer.

I guess you've already tried using the downloader. In case you haven't, you should try that.
If it's also not working with that tool, do you have this problem only with EE2 or other GOGs as well? Also, have you experienced this on other sites?
