(Converted) in the file name is pretty concrete evidence that it was NOT created inthe version you are using to open it.
There are some potential version numbering issues. Version 3 was CS, CS3 is version 5. CS5.5 is version 7.5. It's possible that an update to CS3 could make the file open as (Converted), though I honestly don't recall seeing that.
In any case, you can see the entire file history if tyou hold down the Ctrl key while selecting About InDesign for the Help menu in Windows, or holing down the Cmd Key and making the same selection from the InDesign menu on Mac.
If you tell us the OS, we might have some more ideas for why other things don't work.
Right, I'm on Windows. Sorry for not including that in the original post.
From the doc history, it's telling me that the file was created on version 5.1, so that checks out. it also says it's opening as a copy, which sounds like something that could prevent me from making changes?
Thanks for the quick reply.

The last publicly released version of CS3 was 5.0.4 build 682, so if you see version 5.1 something is not kosher. Are you sure you are not looking at the version of WINDOWS rather than ID? The dialog can be a bit confusing.
Opening as a copy would be normal if it's being converted.
What version of Windows are you using?
Hmm, the program should be legit, it's a computer at my school.
Scratch that, it was 5.0.4/682. My fault. 5.1 would be the OS version. I can't check it specifically becuase, suprise suprise, the network Admin disabled looking at Properties. The system I'm on now is running Windows 7 Home service pack 1, if that helps.
To first rule out certain obvious things -- these items aren't all on a Master page, are they? They aren't locked on the page? They aren't on locked Layers?
