Anyone else getting a bug that whenever I zoom in the f1 view, the blue circle jumps to the bottom right of the screen and the objects vanish?
I can't replicate it right now, but I think it's a known issue. When in F1 mode, you can always use the mouse scroll to zoom in or out.
DaniGalaxy, your graphic card is a professional card with 1024GB of VRAM, was good enough in 2010, but I'm afraid it doesn't meet SpaceEngine minimum specifications.
WiseXWarrior, you too, I'm afraid your Radeon HD 5670 doesn't meet minimum specifications for the program to work.
imbamakaber, you could try and disable temporarily your antivirus, as it seems an error appearing with several games on Steam, not related exclusively with SpaceEngine. Antivirus programs, as they do, are very picky with their predictive algorithms, to the point of removing perfectly fine operating system components at times. If it works, you can usually place SpaceEngine in an "ignore list".
If it doesn't, well we'll try something else.
