Beware - just a caution that whichever email is used for registration is prime thereafter.
You initial mode of contact should be using the built in help report facility as this generates an auto-reply which proves your comms to/from HRMS. Once that route is firm then the direct mail method can be employed.
The built in reporting also sends various files to aid diagnosis of a problem.
One final ‘repair’ may be your internet provider as there was a long gone discussion from Oz where the ISP proved to be the stopper.
If all else fails you can get HRMS to log onto your PC remote using Teamviewer. You can watch whilst they rummage around and fix it for you.
I am a college student and I use my college wifi. But I also tried to use my mobile phone data as a hotspot, it also didn't work. So I'm pretty sure that it's not due to my ISP.
The built in help report didn't work, as I stated repeatedly earlier. I also emailed HRMS using my primary email address, but I haven't received a feedback after three hours of sending the email. I don't know what's wrong. Should I send another email using different email address?
