PROBLEM with the 2004 tracks of patrickf1...

I have a problem with the tracks made by patrickf1 of the year 2004.
I read a few problems of other people about the monaco track 2004 where they sometimes said something about a gridleft.jip and a gridline.jip file. now í don´t know what is now exactly the right way to install the file packs.
When i follow the instructions as said in the text file and go into gp3 then there is no track shown called monaco 2004 or other added tracks. who can help me???

I've got problems too... I can get the track to run, but without any kind of textures. The layout is ok tough. Any ideas?

The actual name of the jam folder is mc04, not mc04jam.
The same idea for the 2004 Montreal by Patrick, I think.
The jip file should be in the gp3jams/mc04 folder. I said gp3jams, not gp3jamsH
Also, turn the "catch menu strings" option on in gpxtrack.
