Cause

Could be due to keystore corruption in mid server.

Resolution

1. Make sure the mid server windows service "Log on as" account is either a local admin account, or has full permission to mid server folder. 
If point 1 is verified, please proceed following steps 
2. On MID server host, stop MID server windows service 
3. Delete the keystore file in agent/keystore folder. 
4. Open config.xml and remove the keystore value. 
ie: 
<parameter name="keypairs.mid_id" value=""/> 
5. Start MID server windows service 

The mid server will start up as not validated. Click the validate link and the MID server should restart and then validated.
