I downloaded the akami since it asked me to do so, and when the downloading begins, it right away says it's completed.
When I check the folder, 10kb size file is created and very surprisingly not working.
Apparently, the workaround is to use Opera browser to avoid the silly download manager stuff.
Thanks, but I actually just reinstalled it after uninstalling it clean, and it worked.
With IE that is. I actually tried with firefox before I uninstalled it but it has same issue.
Anyway, thanks for your help
