Steam let's you redownload games.
Origin does it
GoG.com does it
Basically every digital distribution outfit on the net does it. Is this going to be the same with WOFF? Lose it and you're screwed? That's ridiculous, sorry I forgot to account for harddrive failure, geez.
Normally when this happens folks simply drop us an e-mail on support with their original order number and we simply arrange a re-download.
Quite simple really - no need to lose it in the forum.
Also one can buy redownload insurance which was a nominal (pittance) amount on top of the price you paid for HITR when you bought it, which allows for unlimited untimed downloads...
Finally we dont control the distribution.....Avangate do.
HTH
