I have had this board about 2 weeks and it is based around a Pic18f4550cpu together with picbasicPro. To download programs I have used the mplabs software via the usb connection etc. I have succeeded in getting the "HELLO WORLD" program to work in hyperterminal etc. I then tried to load a demo in pbp.bas and then to .hex then to pic4550. Unfortunately I ignored the warning about bootloader may be damaged when downloading program as I thought it was write protected, but it is not?. Nothing will download now, and all I get is access violation 00407880 in module etc.

Has anyone any ideas please?

Thanks

ps I have an old epic plus serial programmer, the pic however is surface mount?.
