Try it again? I see the same error quite often but find if I repeat the same steps it's ok the 2nd time round.

HI Any chance to remove the browser cache and try again?

Hello, I would like to ask, you can somehow look back to the old function of viewing printed circuit boards, but not 3D, because in 3D there are many problems with the display. If the Internet is weak, then viewing the printed circuit boards on the 3D version takes a lot of time. Thank.
