Can anyone give me some help?

As I can't post in the correct section yet, I was hoping that someone could help me here. Today upon starting my computer, I get these error messages in GUI miner.

Can anyone tell me what these actually mean and how to fix it? Nothing has changed in my computer since yesterday when it was working fine. Using a sapphire 7850 and GUIminer in Slushes pool.

Is your log in information correct? Workers?

Thanks, but thats not it. As I said, I haven't changed anything since yesterday when it was mining fine. I did double check and everything is correct.

Problem is solved by switching from the GUIminer defaults for Slush's pool to "other" and manually entering stratum.bitcoin.cz:3333, not sure why this made a difference.
