Acrobat DC Pro not working but account is valid

[default7jv4g9ur786q]

My company Temus Pte Ltd purchased Acrobat DC Pro account for me and informed Adobe to merge it with my personal account - julieleelim@gmail.com so that I no longer paid a monthly subscription. The company account I registered is julie.lee@temus.com.  It has not been working properly in the last few weeks. I can do pass protect. I already signed out and re-signed in. It didn't work. See screen shots below.

I meant I can't password protect it.
