Convert your QLab version 2 licenses into version 1 licenses.
Converting a v2 license does not invalidate your v2 license, it just means you'll have a license for both v1 and v2.
Please note: We are unable to offer this service for rental licenses. This is because QLab 1.3.5 does not have a mechanism to fully support rental licenses. The conversion only works for "standard", non-expiring licenses.
