PS2 is being retarded

[JDMFantasy2k]

ok so i've reached this part in NFSU2, i just completed two url's in a row and then i beat every race that was on the map, and then nothing new came up. Like i'm just driving around the city with nothing to do

so i'm 46% done with the game and i've race some people on the street but that only seems to get me little unlocks. So i'm wondering if this has happened to anyone yet. Another thing, i've only made 3 dvd covers, and i think i'm supposed to have 6 by now so if anyone can help that'd be great.

Also i think my ps2 is shitting the bed or somehting because i've been trying to beat this mission in socom 2 and every time i complete it, the ps2 freezes. And it's starting to do it on underground. Maybe i'll get a new one after christmas...
