Is this error on my end, or (guessing this is it) in the script?

Depends, what script are you using. and make sure to look at the location where you have to start the script.

could be many things,

 

some errors for groovy dont show up in eclipse and the client so when it complies it just wont load. An example of this is when you save the .groovy with the wrong name labled in the class (NAME) it wont load into the client but wont show you an error. lol.

You should try run the client under a command prompt and provide us the errors so we can assist you because all the answers that they've provided are guesses what can cause the bot saying "Error executing script".

 

 

 

"C:Program FilesJavachangetoyourjdk1.7.0binjava" -jar osbot.jar -devexit

- Save this as Run.bat and make sure the osbot.jar client is in the same location and is named "osbot.jar" and this will make the client run under command prompt to provide us the error, also make sure you change the jdk to your JDK which you have installed.
