for now my problems is fixed

i did 2 things:

1 - install bearshare - i didnt run it yet
2 - shutdown LW with extreme carefull i.e.: pause all d/l ; wait several min ; disconnect LW ; wait several min ; total sutdown of LW. When restart LW the d/l starts imediatly (even before connect) resuming ok. I wait several min before order to connect.

i totaly shutdown LW 3 times already with good results

What appened i dont know.
Works fine until now.
(i didnt delete .limewire folder)
