install Valentina 2.5.8

[-= JB =-]

I was using v4rev_3_mac on Rev 2.9 beta and
everything was working properly.

Now I am using Rev 2.7.1 & have installed the
Anniversary edition of Valentina which is 2.5.8
(V4REV_2_mac).

I ran the installer and a message said it installed
properly but it does not work.

I suspect this is due one or both of the below:

    1.  I was previously using a different version
    of Revolution.

    2.  I was previously using a different version
    of Valentina.

Given the above situation how can I properly
install Valentina 2.5.8 in Revolution 2.7.1.

thanks,
