I have a database that has been modified using access 2010. Everything works when running from both an mdb and accdb file. It compiles clean and creates both the mde and accde, but they don't run. The application opens and everything looks fine, but when you click on the command buttons nothing happens. Before this started, I had an issue creating the mde and had to create a new database and import all of my objects. The error said "You cannot add or change a record because a related record is required in table MsysAccessStorage". Once I created the new database, I could create the mde, but it doesn't function. The database is used in a mixed environment and it's for this reason we are creating the mde. I've tried this in both 2007 and 2010. The database is a split database. All help will be greatly appreciated. I've searched and cannot find any info regarding this type of problem.
