Missing storage folders in Windows Live Mail

I am used to Outlook Express and it wasn't confusing.  This is confusing as most days strange things occur.  Today, I went to delete a folder marked delete as I already had a delete folder and in deleting it , deleted all of my very important folders which had been under "import" I think as I had moved them initially from outlook express.  They are not under the remaining delete folder nor are they in my recycle bin.  Where are they?  I looked under view, did compact view etc, did not retrieve the folders.  Where are they?  These were all VERY important folders. 

I don't think Windows Live Mail is a good product.  I need help in finding my folders, that is not too complicated.  Please help me.
