You have two choices:
a) Delete old files and programmes from your hard drive then do a defrag, which will get you some extra HD space.
b) Get yourself a second HD.
However, any incomplete files you had when your "DISK PROBLEM" occured will start again from 0% when you resume your downloads.
Also, you can check how much disk space you have by going into Windows Explorer.
The screen print below shows the properties of my (work) "C" drive.
