LCO told to contact Railwire customer care as it is their issue. Customer Care number is busy, will try again.@data.hungry.person We who are on Kolkata NOC in the East region are having an issue with Windows system. Yes, for a few of us it works with no problem but most of us have not the same but similar issue on Windows. As @WandereR said, you can try on differnt OS maybe Ubuntu, Mac or Android. I would suggest you to also raise a complaint to your LCO and MSP to proritize this and know if It is a known issue to them.
