How to recover a deleted document library webpart with files in it?

Question

Hi, 
I accidentally deleted a document library webpart with folders and files in it. Can someone help how to recover it? What do you think happens to the files? I checked the recycle bin, there is no any deleted file related to the missing files. When I checked
the Site Content and Structure, I can find the folders yet cant see the files in it. It gives a message that says "Object reference not set to an instance of an object". 
Please guide. 
thanks alot,

Albert, 
Follow these steps:
1) open page: https://your_pormal/Lists/YOUR_LIST_NAME/AllItems.aspx
2) open page in edit mode -> add webpart -> find your list in available webparts -> add
3) click on the ribbon Stop Editing (Page tab)
4) Now you try open library from Site Content. 
But your webpart will looks not like a when a library was created:
Now follow these steps:
1) Open library settings
2) click Create View
3) Select Standard View (don't select All Items from view templates)
4) Name it (for example MyAllItems)
4) Check: Make this the default view
5) Check: Title (linked to item with edit menu)
6) Click Save button
7) Now you have new View (with new address)
8) Open page https://your_pormal/Lists/YOUR_LIST_NAME/AllItems.aspx
9) Open it in edit mode
10) Open list webpart in edit mode
11) Set Selected View to MyAllItems
12) Toolbar Type to Full Toolbar
13) Click OK (after this step it may still showed in "wrong" style)
14) Click on the Page tap - Stop Editing
15) Check result ;)
