I now have the 8.15a version installed and that cured the errors.

I am now trying to get MCS easyhid to work. I have copied the 18f4550.bal plus most all files from the USB18 folder to my c:\projects folder and am now getting the usual "error:Macro USBNIT? Not found in macro file" together with the other three errors usbservice, usbin, usbout.

Reading a thread 10409? keymuu had similar problems. Don't think PBPUSB18.MAC is required? As an idea I commented out the line LIBRARY PBPPL18L in the PBP/18f4550.bal file. This gave the following errors:

Error:No library statement or library parameter
Error:No library statement or MACRO parameter
Error:Unable to open file PBPMAC.INC

I have done a search for PBPMAC.INC but can't find it.

Any suggestions appreciated-thanks.
