I started building this MP3 player from a shared offering here though there's little of the original left! It's been working on PC and WM5 device OK so far, but stopped today. Latest changes have been addition of some buttons of very modest size. So I am baffled as to why I get this failure on my device which reports 46Mb "storage" and 25Mb "program" memory. I'm running the program itself out of the SD card. I think I've attached all the files needed to build it as well as the built device EXE. Any advice, please? TIA, Mike.
