and that error happens when the game is protected from debugging. (e.g another debugger attached)
One method that sometimes works is using the kernelmode read/write process memory and call the systemcallretriever once, and restart ce. Then you get a message to remove the old debugger.

A better option is go to settings->extra and enable "use kernelmode debugging when possible" You can then use find out what accesses and writes without attaching a debugger
