This can be due to a no. of raesons
1=>
Check you run your project while database file is open.
Close Access file and then run.
2=>
It is used by another Process.
Open Task Manager and check if any or current application(that used same database) running and you tried to run again.
Kill that process and then runs..
Hope It Solves your problem.
