I set up a simple Access database on my laptop at home about nine months ago (Access 2007) and took a copy on a memory stick to work on at work. Since then I have been entering data at work and bringing a copy home to produce statistical analyses. Suddenly I cannot open the database copy on my laptop. Access gives me an error message saying that the file cannot be opened and may be corrupt. It opens fine at work (Access 2010) but not on my laptop. The database contains about 650 records and is about 1.1 Mb in size. Any ideas?
