Every time I try to download a file from Subsim, whether I just downloaded, or have not downloaded in hours or days, get the following message and it is now officially driving me up the ffffing wall:

Slow Down! You are trying to download files too quickly. You must wait 3 seconds before you may download another file.

Sometimes it says 2 seconds, other times it says 1 second. But it is a cruel joke on me, because it doesn't matter how many gddmn seconds I wait, I get the same message over and over again.
I have tried turning off every Firefox add-on without positive result. I switched to Internet Explorer, and I get the same thing. I am not using any download manager that I know of.
All I want is a decent freaking skin for my U-Boat. Can someone give me some insight into what I crime I have committed against Subsim in this life or perhaps one previous to be so cruelly prevented from downloading files?
