frequently lose all shortcut keys after saving macros

Hey all.

I have two computers where I'm regularly syncing a set of macros for MS Word. The easiest way to do that is to open the vb editor and paste the whole thing in from notepad.
Then I click save (or Save Normal I guess it is) and close it.
But then....
the shortcut keys I have assigned to the various macros only work until I close Word.
When I reopen Word, the macros are still there, but the shortcut keys are gone.
Takes me a couple of minutes to reassign them all, but happens fairly often.

How can I avoid it?

Also, I read somewhere that in Office 2003 and before, you could hold down the shift key and click on File>Save All and that would preserve the macros and the shortcuts in addition to any open documents, but I have 2007 in one computer and 2010 in the other, and Save All doesn't seem to be there anymore.

Thanks
