[Drive pool not allowing access to folders/files]

Hello,
I have been using DP for a couple of years now, has worked great.
However, couple of days ago I received a drive disconnection notice.
Rebooted, checked all connections,drives come back on.
After that, it was VERY SLOW opening folders (green bar "working on it").
Last night it began to deny file modification permissions, adding folders, etc. Permission denied.
Ran the troubleshooter before bed, when I saw it this morning it had error-ed, and now it will not let me in to my folders.
Product is licensed.
Win 10 Pro
Thanks, Stay well,
John

Hello,
My pool is filling one drive up at a time,  getting drive full when adding files.  I want them to fill evenly...
Help! 
TIA,
Happy Holidays!
