How do I get rid of the red crosses please

My husband set this mybooklive thing up years ago. He died last year. I do not understand it. It used to work. I have important stuff saved there. Suddenly and for NO reason I cannot access these drives. I have absolutely no clue what to do and discover to my horror that this is a legacy product with no support. I do not understand the online manual I do not even quite know what operating system I am running - he did all that stuff. It might be wondows 10, but how to tell ? I have poked about in control panel but nothing helps. I cannot even access WD …I use my email and they dont recognise me. What can i do please ?

Please someone reply this thing has all my data !
