Sweet Pool error, game won't open

1 Attachment(s)

I hope I'm writing in the right place. Anyway, I was playing Sweet Pool and got the save error. I looked the forum and saw it was normal and everything so I just left the game open when I wasn't playing and would come back later to play from where I left but yesterday I pressed "F" while playing (in Lamento it was the key to make it full screen so I guess it is the same for this game?) and my computer screen went all black and I could listen to the game sound but I couldn't do anything, not even the ctrl+alt+del worked. I had to restart my computer but now when I try to open the game it won't work? It shows this message

help please? ;-;

The message says:

"Please mount the correct disc to play."

Did you mount the disc and run the cracked game file? The game application might have refreshed itself being idle for too long.

Try running the game from the setup file in the original .iso disc image.

oh hahahahahahahahaha yeah it worked. thanks!
