Keyclone stops sending keystrokes

Hello im having a problem with my keyclones, im running on 2 computers and havent had any problems with keyclone untill 1 day ago when it started to lagg and almost 90% of the times it wont pass keystrokes to my slave comp or it will only send half of the keystroke.. and sometimes it will just freeze on one key and wont let it go.. ive tried opening the port im using but it wont help..

yep im sort of getting the same. after 10mins its starts getting sluggish and almost toggling keys on and off, after a couple more minutes it stops sending altogether and in the keyclone screen it no longer shows it as being connected to any other pc.
