Halion 6 causes song load error

Halion 6 licence (or lack thereof) causes errors when loading a song. Happens about once a week. Is fixed by running elicenser maintenance. I purchased a new USB dongle to see if it helped. It didn’t; and I’m annoyed at spending $70. This only happens with the paid Steinberg VSTi, of which I have a few. Does anyone else have this happen? I’ve tried different ports - makes no difference. The error never involves Cubase or Wavelab. It’s always Halion or Groove Agent etc.
