multi language cd cast libs prob

[trunky]

I am making a multi lingual project to be distributed onto cd rom, i am using multiple external cast libs to swap on language selection eg

on mouseUp me
set the filename of castLib "media" to gDriveletter & "\media\dir\english\english.cst"
go to next

my problem is that the changable media is an external cast library and is referenced to my hard drive thus not working on a cd rom eg

media is referenced in cast library properties I:\media\dir\english\english.cst

how do i get around this referencing problem, if i change the cast to an internal library it will not swap

please help
