I don't think it'll ever be fixed as the fix is incorporated in the new version... thus the old becomes obsolete ... plus it would require some rewriting of the old PR v3 which would seem kind of redundant.

Maybe you can PM Meredith and ask her for some help to install PR v3 though (she can remotely control your comp thru some software to help you out I think). If you really have no clue on working your computer, can't you ask someone else nearby to do it for you?
