Microsoft Access Errors were encountered during the save operation

Hello friends!
I met an error while using Microsoft Access. I am not able to save the record that I added into the database. The error message tells me" Errors were encountered during the save operation. Indexes were not added or changed". See below the screen shot of the error for better view of my problem.
Microsoft Access
Errors were encountered during the save operation. Indexes were not added or changed.
I checked on the Microsoft Access whether I have some rights on the database, but the problem still persists. I tried rebooting my computer and after which I tried to do the same task, but still it cannot save my file. Please help me with this post. Thanks a lot.
