What EP's have you got? The terrain paint situation was improved from OFB (think it was OFB) - could try adding OFB if you don't have it.. Wonder what would happen if you took out the lot where you deleted that terrain paint out of the lots folder.... should be the last one edited if you don't know the lot number.. Move it out and try. hope somewone more awesome than me can help.
I have uni, nl, ofb, glm,and pets....I thought that that was fixed too....and yes my games are patched....I also deleted some doors and windows, some that I may have had "inuse"....as far as the terrian paint I deleted I don't think I used it in any of my lots in that neighborhood but it may have come with a house I had downloaded....don't remember...I sure hope I can get it fixed....thanks for the help....tgdrysix
