Are you renaming all the relevant files. Check that you have
renamed the .cnt, .doc, .hh, .hpj, .hpr, .rbh and .rft files. There
are also a number of other files that can be deleted as they are
recreated. Finally the .hpj, .hpr and .cnt files need amending
using Notepad to update any references they have for the old
project name. The RH help has a good topic listing the steps you
need to follow. Just use an index keyword of "renaming".
