I was able to install after a couple of attempts. Ran it for a short time and didn't have any problems but haven't had time to do a whole zoo. Hopefully it will keep on working.
From Jay: The "bonus animals" are in the Updates folder. But different parts are in different files. And depending on the intent, the answer might be to use APExp 3.2 rather than to look at anything in the Updates folder.
We don't have the capacity to accept a card directly, but I do think that Paypal will process through debit. A check is a fine way to donate; it will just take a while to get it processed through the bank. A check can be sent to me or Cricket by mail. If you don't have our mailing address, just send a PM and we can help.
Thanks!
