Cannot Install Game; File Copy Error

[nylock10 0]

Hey,

When I try to install Armed Assault (1.05 English from SprocketIdea), I get this error:

File copy error (CRC does not match).

C:\Program files\Bohemia Interactive\ArmA\AddOns\misc.pbo

What does that mean and what can I do to fix it?

I sent an email to support(at)softwrap.com a few days ago, but they didn't respond. Do I need to re-download the .EXE file?

I've never had a problem with this before.

When I visit the link included in the email from SprocketIdea to download the program, I get a "UID is not authorized" message when I want to begin the download.
