My adobe license was renewed by the organisation and I've lost all my cloud documents

Having files only in cloud storage is not a good idea
This won't help the original person with lost files, but For anyone else reading this...
Do NOT have your files only in cloud storage
You should always have an extra copy of all files (or TWO full copies)
Computer crashes or account changes happen, so use an external drive for copies
A USB flash drive to keep in a safe place... there are many brands and sizes available

.
I use a Sata docking station and SEVERAL 'bare' drives for backup of my desktop computer
There are many external drive devices, this is the one I use

renewing a subscription wouldn’t cause that unless something else occured.  eg, do you have a different account ( https://account.adobe.com ) now than you had previously?
