Help! How to restore from backup?

[mantonioes]

Hi, all.
I have just downloaded a Jedi Power Battles backup. It is a .rar file with five files in it: .ccd, .img, .cue, .sub

I have copied all files in one directory, then run CloneCD.
I get a CD labeled SLES_026.11 with the following files:

z.000
System
File.001
File.002
File.000
Sles_026.11

I read somewhere that now I had to combine all File.* into an ISO. When I run the DOS command copy/b file.000+file001+file002 file.iso, I get an error.
Also, I cannot copy the files from the CD to my hard disk, I get an error too.

I have done the copy again from the original .rar files with Nero, and I get the same CD as above.

Can anyone help me, please?
What can I do to restore the original game?
