I told you to reinstall Tremulous because you did not really give out any information about your problem. The information you supplied was just the generic error message that Windows poops out when a program crashes.
What client were you using? In other words, using the stock tremulous.exe that comes with the distribution of 1.1.0, or a backported client, like the one from tjw or trem-servers.com?
Also, please do not create a poll when there really is no need to. People will stop by and try to help you, even without a poll.
