Creating users on my My Cloud PR2100

I created a user and share on my PR2100 and for some reason when I try to access the share a login box comes up and I type in the credentials I created and it does not let me access the share.
Thanks

@warren65 You may get faster help if you post in the correct sub-forum for your device. You have posted in the My Cloud Home sub-forum. If you have updated to OS5 then post in that sub-forum, see second image.

Thanks, I moved my post.
