We are having trouble with a file which we cannot bring from backup. We are using SS10.
When trying to open the file, we get the information box stating "Unable to open design file. "Please contact your local site administrator or technical support provider for further assistance."
When trying to reference the file in a different file, we get "Unable to find model "(null)" in Control.dgn". (Control.dgn is our file name)
Any help would be greatly appreciated.

This error means that model index is corrupted an issue that was not addressed in v8i era and still comes up. File is easily fixable at least you will be able to open file even if something else will be missing.
If you are not willing to share the file here is the instruction how to fix - https://communities.bentley.com/products/administration/f/product-administration-forum/144134/unable-to-open-design-file/447193#447193
Key-in: MODEL REINDEX would work but as file can't be opened this key-in doesn't work.
