FAQ

I have downloaded a CHM file but i can not open it. It keeps showing a dialog box titiled "Help" with the content as follow."Cannot open the file: ...."


This is Microsoft Security Issue, read this article: http://support.microsoft.com/?scid=kb;en-us;902225

If I use the account at my office when I'm working and then at home when I leave office you will block my account when identify ip is not the same?


No, only simultaneous access is forbidden. You can use your account at home and at your office (or other places) until then do not access yet to it simultaneously from different IP/computers.

I'm a basic member right now and i'm interested to become a pro member. But i realised that those users who are downloading using the same IP address as me will be recorded. So even if i don't download anything, my quota will still be used by other users. Hence, if i become a pro member will this still happen?


No, this is only basic members limitation:
Basic accounts counts all downloads within last 48 hours (your account or your current IP address).
Pro accounts counts all downloads within last 24 hours (your account only).
