Oh, sorry, I forgot to mention that problem in the readme file. What you need to do is to download RPG Maker 2003 runtime pack which I just uploaded. After executing, the file will ask you to add it to your Windows registry. That should work ;)
Allright, I executed the RTPen.reg file and I could run the game! But... I was talking to the drunk teacher, and I believe a fight starts there and... It crashes to Windows: "The file [weird letters] cannot be opened".
BTW what you uploaded is not the actual RTP, right? It's just a .reg file.
Ok, I think that the only solution to your problem is to google it. My game tester had checked that issue and the game worked just fine. Sorry, but I can't help you :(
