a month ago i got a new computer: an LG notebook R405 with intel pentium dual-core inside.....
i have been playing CC on it since then but yesterday i encountered a problem, when i was playing it suddenly started lagging like hell and eventually an error went of and i got a message that said that this game does not perform well on computers with dualcores.....
so i started playing build 21 which i still had left untouched with all the mods still left but i got the same error there to.....
so why does the game show that error after a month of playing with no faults at all until now, i really want to continue playing but i dont know how to/where to install the new cpu driver that the error requests.....

It would help if you would give the exact error so people could identify the problem...
