copying Comanche4

[sennagun]

Having bought Comanche4 (great!) now I want want to have an backup-copy.
This is not working with Easy CD -creator, not with CD-clone and also Nero locks up.
They all have a problem with 2 (dummy ??) files.
Unpacked/ installed Microsoft Explorer sees it as big as over 3 Gigs !! (on the original they are approx. 300 Mb
Does anyone know how to copy Comanche4 or have had similar problems with the newest copy-protections with other games ?

Thanx
