Hello Elisabeth,
Not sure which version of CW Suite you own, but if you have a perpetual one "CWP-xxx..." the license should work without any time limitation.
If you buy a CW Suite you automatically get support contract which is valid 1 year and which may have some benefits for you ( e.g. you automatically get a new license if there is a new version released).
I assume this support contract has expired. You can of course extend it byanother year if it's your project requirement (see this video How to renew your Software|NXP)
Hope it helps.
Stan
