Hi There, I've just upgraded from PIC Basic Compiler to the PRO version due to the obvious limitations with the standard version. I had PBC working great until I ran out of code space etc. But now I cant seem to get even the simplest LED blinking program to run. Everything seems to compile just fine, yet no joy in flashing an LED. So before I start ripping my complicated circuits apart on my breadboard I thought I'd ask if there is anything really simple that I might be missing in the upgrade process. Can anyone spare some time for your newest newby?
