That means the freezing has disappeared as for now !?!?
That your connection drops,....hmm,....try deleting the LW preference folder (called "LimeWire" for versions 4.12. located in the hidden Application Data Folder at C:\Documents and Settings\Administrator.<your computer name>\ Application Data; and " .limewire " for versions older than 4.12. usually located at C:\Documents and Settings\Administrator.<your computer name>\.limewire)
Delete it ( or them, if both are present ) while LW is completely closed, i.e. also in the system tray.
Afterwards you'll have to reconfigure LW starting with "Language".
