OK, what happened was last week when we battled the hack, I changed all my passwords and log ins everywhere, including my paypall primary email addy. We also replaced all the pages on the site and others with previous saved and safe versions. I think somewhere here we either uploaded an old donation button pointing to an old email addy, or forgot to update it with the new addy.
It should be fine now, and take you to a paypal donations page saying "Help keep the SAS flying in 2012" or something like that. Please let me know how it goes. And, sorry for the hold up.
cheers!
