Hi:

have saved a number of acrobat reader expense claim documents, among other things, on my desktop over the past several years. 

Today when I attempt to retrieve an Expense Claim document, I get the following message: "There was an error opening this document. The file is damaged and could not be repaired".

This has materialized 'out of the blue' and I can still open other documents, including other acrobat reader documents.

Has anyone experienced this and can you advise please?

Thanks,

Barry
