Have you tried deactivating your licenses on the other devices and then reactivating the one that you are currently using? Or are you using an actual ILOK device?
Check your activation numbers limit online, deactivate the ones you don't need, or if you are just using one PC deactivate them all and then reactivate them again. You won't lose them by deactivating them, you are simply saying that is not used anymore. They have limits on certain things.
I don't have an ILOK device, but I have 5 software's on ILOK and they don't require an ILOK DEVICE, but they do demand that I use them on one PC because I don't have an ILOK device.
Anyway, I hope this helps. Good luck.
