I have an expansion for Groove Agent (Colliding Worlds) that uses e-licenser. How do can I make sure that it keeps working when the e-licenser closes down?
It will simply continue to work, because the shutdown is for the Server infrastructure at Steinberg, not your eLicenser.
I don’t know If you have a USB eLicenser or the Soft eLicenser. I recommend to use the USB Stick, because a Soft eLicenser is linked to your current Computer, the dongle can be connected to other computers as well.
You should also check the voucher section in your Steinberg profile, if there is a voucher to update your expansion to a Release that supports Steinberg Licensing. If there is none ask support If there is one you can get.
I see indeed there are vouchers for all the older expansion packs. I completely missed that Vouchers tab earlier. Thanks!
