Sa7ar,
I am stuck, I am trying to convert the database to an earlier version, but it won't, actually I used some controls and features which only works with Access 2010, you got to try this
- Open Microsoft Access 2007.
- Create a new Blank DataBase .
- Click OK.
- Goto External Data menu and the Click on the Access Button.
- choose Import table, queries, forms etc....
- Import all the objects from the previous database to the new one.
- Save the new database.
- Close access and try to open the new saved database again.
I hope you can run it because it will be really what you are looking for.
else, the last option, you have to install Access 2010 and run it and for sure no problems after that things will go ok, else if you have a firend who has Access 2010 you can open the database on her/his computer and check how it is done and try and do it again on Access 2007
