I agree with Reyalp that figuring out why STICK didn't work (or better, using CHIMP) is your next step. It's also worth pointing out that unless you are using a Mac, Linux, or the latest version of Windows 10, using a card with 2 partitions is a pain - you have to keep switching the active partition (which must be the small FAT16 one to boot CHDK but must be the large FAT32 one in order to transfer photos to your computer). Like OSX and Linux, Windows 10 now lets you see both partitions, but earlier versions only show the active one.
The most common STICK problem is not giving it permission to read and write to the card (required these days for security reasons). The STICK webpage tells you how to do that.
