These are some errors that I get when I click Run. And I don't know if it is the script I am using, but the Seers Village Yews script logs me out after like 20 minutes.

For second one. Load runescape in your web browser first, and let it load all the way. Then change runescape settings to fixed screen, all minimum settings, and highest brightness.
The first one is just an annoying error with MSI, just click cancel or whatever and it eventually works, except Simba is frozen, but the script still runs.
