PSX Bootdisc/PS-X-Change 2 Help

[CloudStrife2003]

I have the PS-X-Change 2 for my PsOne and my backups of games like Syphon Filter 2 and FF7 runs fine because it asks you if u want to save right after you finish a cd and you can restart the game with the PS-X-Change 2 and insert the next disc and then continue the game on the next cd but with Metal Gear Solid I cant do so. When im done with the 1st disc of metal gear solid it tells me to enter the sencond disc. when i put the second disc it wont spin or load up. the cd remains still in psone cd drive and then i close the cd drive and still wont load up, and then i tried pressing every button 1 at a time on the psone to see if it loads or spin. but nothing because of this i cant go on in the back up and i need a backup cause my sisters like distroying my stuff! help please!
