Yeah, if you're using the same activation data then you want to use (a) the same version of TurboActivate and (b) you always want to use the most current version of TurboActivate.
TurboActivate is backwards compatible with all old versions, but TurboActivate is almost never forwards compatible. That means you can always upgrade to the newest version of TurboActivate and the new versions will always be able to read the old data. But you can rarely use an old version of TurboActivate and expect it to read data written by a newer version.
That's just how we've designed it (it reduces our costs because we don't have to bend over backwards to make old versions read new data).
Short answer: always use the newest version of TurboActivate.
