Okay, on a more complicated circuit I accidentally had a probe on a wire that was connected to ground, but kept getting the message"Probe can not connect with ground (GND)!". So I kept moving it closer to ground with fewer and fewer components. Finally realized its the error message that is misleading and incorrect.

Also, fyi, the first tutorial listed in the page below is returning a 404 error. @andyfierman [https://easyeda.com/example/Simulation_Quickstarter-iLN8usOaw](https://easyeda.com/example/Simulation_Quickstarter-iLN8usOaw) [https://easyeda.com/example/Spice_tutorials-AysKEWevN](https://easyeda.com/example/Spice_tutorials-AysKEWevN)
