Cubase, Halion 5 E-licenser problems

Hi,

Sorry if this is the wrong place to post this. Was using Cubase 12 Pro as I usually do when it suddenly froze when adding Group Channels. No Biggie, just hit restart. However, when I then opened Cubase I get an E-Licenser error - “Some Content Could Not Be Loaded. Either Licenses are missing or time limited Licences have expired”

Very weird, I haven’t done anything which should make this happen. Have never had this happen in all my many years of using Cubase. Anyway, I thought, ok I will try the E-Licenser Control Center. I could see straight away that none of my licenses are on there. I tried an online synchronization and maintenance but still none of my licenses are there!!!

How do I get them all back?

Thanks
