Invalid Key?

[indubitableness]

I'm starting to get fed up here. When I last reinstalled the penumbra collection, which I bought during the USD $5 sale, my key works fine. But when I try to start the game it demands the key. When I put the key in it just demands the key again. It does this forever. When I check ~/.frictiongames/Overture/hlp.log it says "invalid registration key" or some such.

So I said "Screw it" and went to http://getpenumbra.com/store . I put in my code to download a copy of penumbra, hopefully one that will recognize my key, and it tells me I have an invalid code.

This is ridiculous. I paid for the license of a game and now I can't use it. What the fuck is going on? I'd appreciate some help with this.

Is there an install limit on this game or something? It worked before, then my system crashed and choked on itself and when I repaired it and reinstalled it it didn't work. I'm very frustrated here.
