The address is empty according to blockexplorer.info, May also be that I found the wrong wallet, the one I found starts with 17**, but I think the payout one was something 89**
Have yet to figure this out..

I only have an corrupt iso image of my old harddrive, there are 2 other wallets on it but I can't seem to recover them

Is it still somehow possible to access the old accounts from btcguild?

They must have some backups, no?

I think I have around 28BTC still in my account that weren't paid out.

The reason I never withdrawn them: I lost my btc wallet and thought it was already withdrawn, just found it after years of search and the wallet is empty and never received anything.
