Similar phenomenon have been been reported by others. In one instace, the user had no search field to to type in searches. Quite bizzarre. LimeWire had responded by stating that they were looking into the problem, but had not been able to recreate the problem on their computers. I am not sure if your's fall under the same category, but I know it is NOT the same as others since you ARE receiving error messages. I know I'm not much help, but I just wanted to let you know that you aren't the first to experience something like this. :-)
