lausgarci The lastcrash file didn't attach properly. If you'd like to try again, open the file and delete its first line, which is usually what makes the site reject it. If that doesn't work, you can copy the text and paste it into a reply.
I'd also like to know what lots you're playing on, in which worlds; and whether the game runs better in one of the base game worlds, on a default EA-made lot.
And I'd like a dxdiag as well. Click Windows key-R, enter dxdiag in the run box, wait for the scan to finish, click "Save all information," and save the file to your desktop. From there, you can attach it to a reply using the paper clip (Attachment) icon included with the other formatting buttons.
