It depends on what operating system, what version of TurboActivate, what flags are used (TA_SYSTEM / TA_USER), and a few other things. That's a long way of saying: it depends.
If you tell me the product key for a customer that's using the latest version of TurboActivate (3.4.6) and ...
- Activated
- After a certain period deactivated
- And then re-activated again
You can send me the product key to wyatt@wyday.com and I'll take a look at it.
