Cannot copy "gfx" file to PrettyMap "gfx" directory.

[UssTRex]

I have a "Problem: no styles found!" appearing on my PrettyMap4 Upgrade just installed on my Palm T/X. It said to copy txt files to "gfx" directory on my card. However, everytime I use my "Palm Install" program it said the files are already on my card in my "Documents to Go" program under "Documents" directory and will not install them again.
