As to the activated repeating sound. Check you have the right version. Tell youur security programs to ignore the file or shut them down.
As to the crashing. I take it you read the instructions? As there is a few points that are important.
In the first paragraph that is under the notes section. It points out that you should save because the game may crash unexpectedly. Also it states that you should turn off all features before ending turns or before entering a battle. This reason is to stop the crashes at those points the trainer can cause the game to crash.
I did exactly what you said didn't help me any
