Winrar freezes at 100%??

[SoundOfFaz]

I am trying to unrar a movie I've just downloaded (nzb) In the folder there is one winrar file and loads of other files (c32, c52 etc....) then there are the par files. When I try to extract the winrar file or any of the c32 files (as when I right cick these I also have the option to "extraxt files") it unrars fine but when it gets to 100% it just gets stuck on it, normally once it is done the "extraxting from..." box will go but it just hangs there at 100%.

Anyone een this before?

I tried running the par file and it id its stuff only to tell me "repair not needed" so there doesn't seem to be a problem with the file.

EDIT. Again, I have been hasty with the post as I left it for a few minutes then the "etraxting from" box went so burning now
