OK, thank you to the nice person who emailed me the Mpplus.dll but now my 4.00.00 MPLAB is complaining that it won't accept the new file, unless MPLAB is 4.00.03 or higher. I don't want to get stuck in a nightmare of dll swapping so unless someone has a good suggestion it looks like I will need to download the bloated new MPLAB and hope it works, then spend hours moving and re-organising all my files, complain complain etc. :o( -Roman -- http://www.piclist.com#nomail Going offline?
