Things have been going really well with my CHIRP bootable USB, and I've been able to program and update several radios over the last year or more. Now, not so good:

system boots from USB on my portable PC (running 64-bit Win7 Pro) and I get the usual desktop, but cannot run CHIRP — when I double click on the icon, I get the timer icon for a while and then nothing
thought maybe something went south on the laptop, so tried the same flash drive in my desktop (running 64-bit Win7 Home Premium), and got exactly the same result
CHIRP update operation in both systems seemed to work fine
thought maybe something went south with the 8 GB USB flash drive, so reformatted it and reloaded everything — same result on both systems
tried another flash drive (4 GB), loaded everything from scratch, and got same result on both systems
loaded daily build on laptop and it worked fine

Any suggestions? I really liked the Live USB option, but now…

Sincerely,
