You do not have to use the same version of the software at all.
Better uses the one that is proper cr*cked. Active 5/6, Revo... Version 7 is not recommended, need licenses for all content.
Or, you can just replace main exe from your device with one from compatible packages.

Btw, personally, I suggest "Becker 9.6.8.286435 - Ready, 6 Mar 2013" ver.

Just a note, in addition, it may happen that there is no other version other than the one that was on it can work with BT&WiFi.
