Did you recheck the salinity? Make sure you tap the hydrometer to release any airbubbles that can adhere to the swinging arm.
Do you wash the hydrometer with fresh water after testing?
Does the arm swing freely?
I would recheck with a second meter, buy a refractometer or take it to a LFS to test before trying to correct the salinity in your fishtank.
