Your PD-Chainplate.zip seems to have been downloaded 46 times, so it looks like the upload did actually work. Are you still not seeing in your account, or has the problem resolved itself?

I used Firefox (15.? I think, I'm on another laptop at present) to upload last week - no problem. (All plugins and addons disabled, except maybe Shockwave Flash, adblock, MAFF and/or WOT)
