I was here about 3 months ago, and have been monitoring all issues with this same problem. This is not a support request, but rather an update on the infinite loading screen issue.
Is there any research being done on the reason why the FR application will not start up, and instead we, who have this problem, cannot get past the RSSC loading screen. Can a dev spend some time on this please? I know there are lots of issues, but I have offered payment, also offered to share scree, nobody wants money and nobody wants to help… Please address this before we, who have this issue, give up on FR. There have been a serious number of other users wasting (in my case) weeks - months on this problem, when I am POSITIVE that if someone literally spent a day on this with an end user experiencing this issue, it would be solved and would probably solve other problems.
Please let me know or contact me directly if you would like to get together to be everyone’s hero on a fairly simple issue.
