Missing shared stash

As the title implies. Played D2R last year similar time, came back on this year, logged on, Shared Stash tabs are empty. No buttons or anything to retrieve stash. Talked to customer support, had my time completely wasted. I spend at least a hundred hours building up that hoard.

Online or Offline character?
If Offline: did you switch PC or user profile?

Online characters only. I have indeed switched PCs, but again, I’m referring to online characters.
