Hi ! I just wanted to state that I suffered from the same error message today aswell. SLR App updated itself to the latest version when I started it and afterwards I got the same error message in VR. Blank screen (completely black) and the words: Error loading project data. -> Operation time out.
Nothing more happens.
Then I found this thread here and also tried changing my location. Changed it from Berlin/Germany to Switzerland and for whatever reason now everything seems to be fine again.
Rakly3 was right. I just don't understand why the acutal main menu screen of the SLR App would be affected, anyway.. if it was just the online videos itself that would not be loading - well okay - but with this error I also wouldn't have the possibility to view my downloaded fav videos.
..and I always want to be prepared for day x when the internet goes all out and I can still enjoy my VR porn
