Hi, thanks for replying so soon. I tried replying to your comment, but I received this comment :
The message you have entered is too short. Please lengthen your message to at least 4 characters.
So I'm writing as a reply to thread, sorry about that.
I tried running the mod launcher again without norton protection, but it was the same.
If it helps, the error message was as follows, (it means nothing to me, because I'm a pc illiterate, but if you can help, it'd be much appreciated!)
