I didn’t want to lose my licence, so i’ve downgraded to v 2.8.21 WITHOUT the routing package. So i had ver 2.8 with the basic packages.
Then I installed v 2.9, but still the same error.
To install the routing-test package you should have a router with v2.9rc7 (without routing package).
Then upload the routing-test package and reboot the router, it should install this package.
