Existing Applescripts CS6/CC wont compile

I have some applescripts that i've been using in Indd that wont compile anymore.

I've been using these scripts for years now, but now need to make minor edits.

I can run the scripts and they work ok, but even after opening right away, I cant compile.

my first  2 lines are

tellapplication "Adobe InDesign CS6"

          setmyDocumentto active document

Even if I just open and right away compile, it highlights "document" in "active document"

and I get "Syntax Error Expected end of line but found class name. (OK)"

I recent upgraded to maverics is that anything to do with it?

I'm still pretty much a beginner when it comes to applescript.

I originally created these is CS5 also, which I no longer have, if that is anything to do with it.
