I try starting a script and I select my desired script and the account selector pops up.  I am signed into osbot with my account but no accounts show up in the account selector.... so I can't run the script.  Please help me, I don't know what I should do.

It means your runescape account. You can skip that part with the thing in the bottom right of the popup or you can save your info into the client.

The account selector is used for auto-logging into your Runescape account if it logs out for any reason, you can add an account by doing the follow:

 

Click on the "Settings" cog: 

 

Which will bring you to this menu where you can enter your account details:

 

If you're worried about your account being hacked don't be, the settings are saved in a file called "local.dat" which is located on your computer at "C:/Users/YOUR_USERNAME/OSBot/data". 

 

Lastly make sure you hit the "Save" button to store your account information, alternatively if you don't trust this method still you can click "Continue" when the account selector appears and then hit "Yes" when it asks you to confirm you aren't selecting an account.

 

Hope that helps ^_^
