No need to apologise <em>Gail</em>. :)
Yeah, if you're busy then stick with what works. Were I not in the middle of a large project myself I'd consider upgrading DW but it'll keep for now.
Unfortunately I don't think you can have DWCC2014 and DWCC2015 on the same machine so I'm stuck a bit there as, previously, I'd been using DW8.0.2. Jeez. Showing my age there!
Good luck sure.
