Alas, this is why I get most of my PDFs from DriveThruRPG instead of BattleCorp. I'll usually order from BattleCorps if I have a gift cert or if it's BC-Only material. I've had one too many hard drives fail on me and lose all my PDFs, then have to buy them again because the link expired on BC.
Or you could e-mail customer service, let them know your hard drive crashed, and they'll activate a few more downloads. Sure, it would be nice if it was a permanent option, but I can't complain.
Hmm... I can't remember if I emailed them or not, but it wasn't that I didn't have enough downloads, but that the link expired. For instance, I just picked up the
Field Report: CCAF with the voucher from last week. I ordered it and downloaded it on the 25th, and the link expired on the 30th. Now, if I go to my DriveThruRPG page, I can go through all my orders and download them up to five times. I just prefer DriveThru's method over expired links.
Before it goes further, I'd like to say I *LOVE* BattleCorps, except for in this one regard. If the links never expired, I might order more from there.
