Didn't bother reading any of this stuff but here is my summary of what ive been experencing!
1. nTitles is missing, you are not logged in as a user, only as a guest
2. RGSS file not found, reinstall it, thats what i did.
3. rgss101 (etc) (dont remember the numbers), if you move your program to a completely different computer, this will happen. (way to fix is: reinstall the rpg game from the internet on that other computer and keep your data from your map/game/adventure)
4. Trial has expired, either buy it, or get torrents. I suggest getting torrents, but if your a freak about viruses, buy it. It's $60.00
