Acrobat Reader Error Message When Trying To Re-Save Over A File

This is a quick one.

Ever opened a file, edited it, went to save over the same file to the updated one only to be told the following:

The file may be read-only, or another user may have it open. Please save the document
with a different name or in a different folder.

Well this is because you still have it selected/highlighted from when you originally opened it.

Simply click off that file and re-save again. 

VIOLA!!

Only bad part is it saves it with the new date and time so you cant see when you originally created it anymore.  UNLESS you are using restore points then you might see some in the properties area: right click file --> PROPERTIES --> PREVIOUS VERSIONS.
