I am trying to log into my main computer and it asks me to upload data or log in offline, I choice to upload data and I am told that I cannot access upload to sage drive because another person is logged onto my remote site. I have been to the remote site and know one is logged on and I have even tried logging on there and logging off and that all works fine, but when I get back to the main site I still get the same message, I have tried to log in as the other user on my main computer and it asks if I wish to log off that user from the remote site, when I say yes it tells me that they are busy on an invoice and cannot be removed, can anyone help me please!
