license key won't "stick"

[ninermac]

Hi, I'm administering a Contribute site for about 20 users. I installed and
licensed all of my authors' copies of 3.0 without incident with one exception:
one user's license key won't "stick"--she's prompted for the license number
every time she opens Contribute. It lets her in each time, but it's obviously a
pain for her to have to do this every time. The only thing different about her
workstation that we can think of is that she has Adobe Acrobat, and others
don't. Would there be a conflict between Adobe software license numbers? It's
all I could think of...
