That whole thing is ridiculous.
First, if had you Launcher correctly placed in GameData folder, and you couldn't play because you got kicked every time, you shouldn't move it to any other folder. You had to come to these forums and make a thread about that specific error.
Second, "weird error message" is absolutely pointless and useless way to speak about any computer-related issues. You are supposed always either to post a screenshot of the error message, or post a full and complete quotation of the error message. Everything else goes straight to /dev/null.

Third, the previous remark also applies to "it asks to make changes to my hard drive".
Do not retell error messages with your own words, post direct quotes or screenshots.
Fourth, I believe that "weird error message" is "Please start the game via launcher and keep it running!".
This is what you have to do:
- Move MBIILauncher.exe to "Jedi Academy\GameData"
- Scroll to "Graveyard" and read a entry about "Please start the game..." here: Windows technical FAQ/troubleshooting guide
- If you still have any issues, describe them in detail, providing absolutely all possible information, including screenshot and/or quotations of error messages.
