Getting tons of .dmg verification errors

[thegreatdivorce]

I just got my MBP yesterday, and so far it's been incredibly frustrating.

Trying to download Firefox, 3 separate times, I get "image corrupted" errors when I try to open the .dmg.

This is probably the 10th+ time it's happened today ... errors ranging from "invalid checksum" (from Facetime, downloaded from Apple), to "error -199".

Any ideas what's going on? The same things appear to be just find on my Mac Pro, and they're running the same software.

Already ran verify/repair disk multiple times.

Thanks in advance.

Figured I'd give this a bump, since it seems I've narrowed it down to a network issue.

Tried downloading the same thing once I got home, and it worked a treat.

Now I get to figure out what's going on with my office internet...
