propably, have you got the latest patches on your litecoind?
most of the pools have patched to help mitigate the latest problems
OK it would be good if you included a link to the patches so I could check it if you ask me that way wouldn't it?
I am using windows daemon binary (version 50004) from
here. There seem to be no patches announced...but I would not be surprised if they were just for Linux.
