Since c0uple of months, I am facing the problem of FDM hanging at 99%. See the below screenshot:

This problem is happening randomly and mostly with Microsoft download sites. It stops downloading the files anywhere between 90 to 99%, most of the time it stops at 99%.
I use Free Download Manager heavily to download files, because it provides me better download speed as well as resume support.
It took couple of weeks to try some alternatives and come up with my own solution for this problem.
As a workaround, I am using the below workaround which is working well on my BSNL EVDO Internet.
Option 0(zero):
- Double click on the file which has stopped downloading at 99%
- In the Download Properties dialog box, uncheck the Maximum Number of attempts option as down below:

- Disconnect internet connection
- Connect the Internet connection again
- Open the Free Download Manager
Option 1 (one):
- Close the Free Download Manager application
- Disconnect internet connection
- Connect the Internet connection again
- Open the Free Download Manager
Option 2(two):
- Close the Free Download Manager application
- Goto Connection Properties
- Select the Networking tab
- Choose Internet Protocol Version 4 (TCP/IPv4) and click Properties
- Change the DNS Server setting from “Obtain DNS server address automatically” to “Use specific DNS server”. I provide Google DNS 8.8.8.8 and 4.4.4.4
- Click OK button to close the open dialogue box. It will alert you that the new settings will come into effect after we reconnect.
- Disconnect your connection
- Connect again to Internet
- Open the Free Download Manager application
And, it starts downloading the file.
Sometimes just one option does not work. I need to try combinations of all the above options to resolve the problem. I feel this is something to do with the restrictions on the Download Server, which is limiting downloads from specific IP address.
And this works perfectly for me.
My current system specification is:
- Windows 8 Pro
- Free Download Manager (Light edition) – version 3.9.2 build 1289
- EVDO CDMA based USB Internet Data card (Provider – BSNL)
Hope this helps to fix your problem.

Just after writing above post, when I restarted my Firefox, my DownloadHelper plug-in got upgraded to final version 4.9.10
