I get this same message now, too, for a program that used to work a week ago. I even tried the USB HelloWorld I got running before that and left untouched. No change in the hardware or code. I found an old .bin in my recycle bin and that one still works. Maybe something changed in the compiler?

Thanks a lot for your valuable reply Mr.Luke Johnson. You mean to say the your old.bin file still works?..Means it is able to display the "list of files,read and write acknowledge messages" also?..
