Unable to connect to the EMM server error(77)

Hello,

After an upgrage from netbackup 7.5.0.5 to 7.6.0.1, I get this error (Unable to connect to the EMM server error(77)) when i launch the console.

And, when i launch the following command : bpup -v -f I get this message"Start up of one or more services failed".

Can I install the Master and the Media server in the same physical server ?

Thank's in advance for your help.
