I have downloaded 8 rar files. Topo Hispania v2.03 with DEM(1.827.078.144 bytes) for MicroSD (GPS Garmin) by SinRenKor.

1. Only part 1 is extractable. The others give a CRC error.
2. After executing GMap Tool, I ran the install.bat There is an error message that cgpsmapper is not recognized as an external or internal command.

I planned to use MapSource to upload maps to my Garmin eTrex Vista. Any suggestions of what is going wrong?
