Hi Doreen,
Already did this and was no help. Just sent me the same steps. Which I again did and it did not work. So they tried to download the certificates on one of my computers remotely, again did not work. Result of interaction -not Myob its the company that issues the security certificate and its my computer (yet it is occurring on two separate computers and different companies and only with the desktop app) I need to contact my IT person (small business owner do not have an IT person). This only started occurring with the update. So frustrating.
Thankyou anyway,
Linda
