Activation count exceeded

I just renewed my subscription and installed DS 2021. It is giving me an activation account exceeded error. I did NOT install on a new computer. The only possible thing I can think of is that I did use a year ago the same license on both my work desktop and home laptop. I did however pony up my own money several months ago and got my own home license. Is my home laptop stupid enough to not let go of a old unused license?

Thanks Phil
