Something keeps messing up when I'm installing

[Beebz]

I downloaded the bittorent package and I've downloaded the installer but when I try to install it,
It keeps saying "Error opening file for writing:" and then the name of these files:
c:\ProgramFiles\Planeshift Crystal Blue\updater.exe
C:\Program Files\ Planeshift Crystal Blue\libcurl.dll
C:\Program Files\Planeshift Crystal Blue\libz-cs.dll
C:\Program Files\Planeshift Cyrstal Blue\vfs.dll
C:\Program Files\Planeshift Crystal Blue\xmltiny.dll
C:\Program Files\Planeshift Crystal Blue\msvcr70.dll
C:\Program Files\Planeshift Crystal Blue\msvcp71.dll
C:\Program Files\Planeshift Crystal Blue\msvcr71.dll

And then it asks me to Abort, Retry (it won't work), or Ignore it.I clicked ignore on all of them but after the installation, it wouldn't work either. It would say "Something unexpected happened in Planeshift: Crystal Blue
                         Details:EXCEPTION_ACCESS_VIOLATION at 00c64578
                          Would you like to save a diagnostic file? Yes / No"

Anyone know how to fix it?
(You can tell me over AIM or somethin at Beeb066, I might not be keeping track on the forums.)

Are you installing this clean, I hope?  If not, do so.

Make sure your installer has this md5 hash:
0fe4ece13f699bb45df5bee59bb73031

(Someone else got the same thing, except starting with an 'm'... both worked.  Don't know what's going on there.)

md5 Hash? Sorry, not really a computer wiz, I wish I was though.

I'm downloading the installer again, but without BitTorrent. Hope it works this time.

*edit*

I downloaded the installer again and its fine now, thanks a bunch.
