Hi!, we are using Mass Hunter software to control an HPLC 1200-Q-TOF6520 system.
Suddenly, in the instrument status bar, the window for injector control disappeared, without some wrong manipulation.
I tried to config the HPLC with the tool Instrument Configuration, and it was successful, but the window in MH doesn't appear.
All connections are ok! so I cannot understand what could be happen.
I really appreciate if somebody can help me with this problem.
Regards.

Pato.
