I think the guy Pitrik who said hes on "100mb connession" or something means his download connection speed (ct! ITS CT! ahem) is high. I personally am on a 200 Mb connection (200 megabits, which is basicaly 25 megaBYTES), so some of the mods here download in seconds, and I... have a high mega cap. The "limit", is referring to the total data you can download, not how fast you can download.
On the other hand, if the guy DID mean his DL quota, not his speed, then thats just terrible. I would hit that in half a second!
Waiting for the OP to be updated for 0.21 and MaimLain to mod it first... that might be the problem with the saves - older saves made with modded versions of DmD.
edit: It was Pitrik who said 100mb connession. Dude, its connection. That spelling error was just painful to read., for some reason.
