Hi,
Then simply change the location (path) and/or filename of your sourcefile so that the complete path and filename is less than 62 characters - simple as that.

As an example, having your source files in project folder in a PIC folder in MyDocuments is bad as the full path might be:
C:\Documents and Settings\Nurulhaiza\My Documents\PIC\MySDFSProject\Source.pbp which is 78 characters. Moving it to C:\PIC\MySDFSProject\Source.pbp will work as the path and filename now is 31 characters.
