Help with running games

[Omnipresent]

I recently got PCSX2 and everything has been going well except for one problem.

Here's the situation: When I try to play (No matter if I try either Boot CDVD Fast or Full), the black screen would pop up as if I were to play the game, but only for a brief second and then another box would open and this is what it says:

File Not Found
Path: IsoFileSystem

Now, I understand if I made a simple mistake and all I have to do is put my games in a certain file, I would appreciate the quick and easy help. However, if my problem seems more complicated, yet still solvable, I would appreciate it.

Thanks to all and any who help me out.

Do you have an iso selected? Under CDVD select iso and browse for your iso file. Then try.

Already tried. Still brings up the same message.

Try right click on PCSX2.exe and click run as administrator,it work for me.
