Did you EVER figure this out? I am having a terrible time because I don't know what a Vendor ID is. It is not accepting my Adobe ID info.
The Adobe ID is you Vendor ID. If the Data not accept, reset the password of you account and used only letters and numbers.
I found out my issue was that it was showing 3M Cloud as my vendor for
which I had no ID or password. I deleted 3M Cloud from my computer and then
they gave me the possibility of entering my Adobe ID and password instead -
whew! No more making multiple Adobe accounts or changing my Adobe password
This are Good.
I had same problem,too.But I changed my adobe ID password then it worked!
Make sure your new password isn't too complicated (the shorter the better).
