Of course it's always better that you post problems on the forum on my site, so other users may also benefit from it, but I'll make an exception
ChunkyMunky: in which box are you typing the info?
Sean Day: this is probably due to a connection problem that the setup file got corrupted, since other people were able to download and install the software correctly, I suggest you retry downloading it.
Crazyboy: press F1 in the 'Feed Me' screen and you will get all the explanation you want to activate the reminder.
Oh and thanks for all the appreciation, it means so much to me!
