Can you make your project - or a version that shows the same problem - public? Alternatively, you can share it with the support email address using: [**Project > Access Control**] [**Project > Access Control**]:https://easyeda.com/Doc/Tutorial/share.html then we can see it and try to run it to diagnose the trouble. When you say: "Even when I click Simulation Results under the green dude, all that happens is that a blank window ... pops up." is there no text at all in it? It may be that you have made a typo somewhere such as entering too many parameters in a voltage source or entered an invalid character in an expression. Another possibility is that you have missed, added an extra or incorrectly positioned a bracket in an expression. This may also indicate that you have mistyped something like a parameter definition in a `.param` statement, for instance leaving out an opening or closing curly bracket
