Thanks, Glennos, you 'da man. I searched the Forums as well, like someone else in that thread, but didn't see anything either (helps to use the right search terms, though). What's really odd is I had the cash for full price on the 5 planes -- I wasn't counting on a discount to make the purchase so I'm not sure why it picked me up. Oh well, it finally worked so who cares?
Well (all red-faced) I don't know how but I tried it again and now the purchase went through. It's been hours since the first time (not like I have no patience and gave up after 30 seconds) but now it works.
So, thanks to the admin's that got me off the Bad Guy list! :shappy:
