well i do these restart gc if your ct cant find the addresses normally i only need to restart once...
but I noticed this...
if you open YM, or other programs and start MLE then GC you and find the addresses again... then close other programs then restart MLE and GC your CT table cant get the addresses but if you open the previous prgrams the is open with your GC at the same time your CT table should work... well thats what I do so i dont have to restart doing sudden again..
