Creative Cloud thinks I don't have an Enterprise ID. No way to switch

Long story short. I have had CC through work, since 2015. Initially only two of us had a license. Gradually the whole dept. moved to CC. Yesterday I wiped my hard drive (Mac) and installed Mojave. Creative Cloud seems to think my work email is a personal account and gives me no option to switch to Enterprise, so all the apps I need to install, to keep working, say Try or Buy.  None of the help articles help me. And our IT people have no suggestions.
