need help

im using craxtion 2 make a multidisk game. but when i try 2 add an ISO i get an error messege saying "this is not a valid XDVDFS iso" what does this mean? and how can i resolve it.

 

how many multigame discs are there?

not many

 

i dont understand what u mean. i normally put 3 games on a disk at a time but 4 some reason this error msg comes up

 

o you said mulitdisk game, not multigame disk

 

o sorry my fault i spelt it wrong. ive sorted it now anyway i used extract-xiso 2 make the iso again
