I have been having this problem ever since I installed version 3 in which upon opening the application, it gives some sort of error message which will go away after pressing F5. I just upgraded to the newest release and now the error message has changed and refreshing no longer seems to work. The error message is:
{"type":"error","severity":"WARNING","message":"The service did not respond or could not process the request"}
This morning I was able to get the F5 to work, but I had to press it at least 67 times. I see similar users have been experiencing this issue but all of the solutions seem to be F5. When this doesn't work, what are some other things that can be done? I have already tried a fresh install.
