IN NO MEANS TOUCH THE LENSE…
unless you wanna mess your PS2 up. The only thing I could think is the game isn’t meant for the region of your PS2, eg. US game for Jap PS2 etc etc.
If that fails, take the game back and get a refund.
BTW why would someone buy the same game twice?
If your PSX cds don’t work and they are brand new. Try putting the PS2 in it’s vertical position and have it read the disc from that point. If it does not read it at that point, there are two things you can do.
1. Try other discs and see if they work, if they don’t work as well as they should, send your PS2 to the shop. If they work, get another disc or refer to number 2.
2. Get 2 strips of masking tape and stick them about 1/2 inch from the center of the disc parallel to each other
So it would look kinda like…

in the center of the disc.
To explain this, CDs are somewhat lighter than DVD discs. In fact, it’s mostly meant to read DVD discs rather than CD discs. The CD jumps in the tray because it’s lighter and causes the disc to not load correctly. The tapes will weigh down the CD a bit and hopefully will load the disc.
I hope that helped you a bit.
