pokemonhackerforever, your friends problem is that he/she doesn't have the RPG Maker's RTP installed in order to play (Considering your game was made with RPG Maker)
btw, I really really need old game complete tilesets (Green, Red, Blue, Yellow, Gold, Silver, Crystal) and also Ruby/Sapphire & Emerald for my sprite comic. and I don't mean RPG Maker tilesets but a full tileset like the johto and kanto ones that were posted in the Game Development Resources thread, if anyone has them I would be very thankful if you could give them to me, otherwise I'll have to rip them, Green to Crystal shouldn't be a problem, but Ruby/Sapphire and Emerald just have too much stuff and I get confused T.T
thanks in advance
