Alec is pretty busy and probably buried in unanswered emails...
Email me at chrissy at infiniteammo dot ca with your name, the email address you purchased the game with, and your reference number from the purchase. I will make sure it gets done 
My download got reactivated yesterday, thanks to you and Alec. I'm grateful for you help.
Problem is, the link Plimus sent me isn't working

. When I tried to click on the download link this morning, I got this message :
"Cannot download
This product is no longer available for download, this may be due to the maximum number of allowed attempts exceeded or the allotted time.
Please contact the manufacturer of the product for support."
I received the email containing the link to the download at around 5:00 PM yesterday and I clicked on it for the first time this morning at 7:00 AM, so 14 hours after receiving the link. According to Plimus support, the link expires 24 hours after being activated, or after 3 download attemps, so this doesn't make any sense.
Of course the first thing I did when I saw that it wasn't working was contact plimus support and select "Download issue" from their support page, but it seems that all they did was forward the email to Alec (admin at bitblot dot com, of all places) and then tell me that I should give him 2 days to respond

Seems Plimus can't take care of anything themselves

... guess I'll wait and try the "Non-responsive vendor" option again next week, maybe now that my download has been reactivated they'll be able to help. No point in trying it during the weekend since I'm stuck with an unstable dial up connection at home.
UPDATENava got my download reactivated, and I was finally able to download the 1.1.1 version

So thank you again Nava for being far more helpful than Plimus

And now I'm off to play Aquaria!
