Hello Nilla,
I saw this issue since version 7.0 but only when using the 7pin to USB lead, matter of fact I posted the following topic "7pin to USB lead", my mistake was not to mention that such error messages did pop up.
now, my question is,
 is that error found with both CG150  and the 7pin to USB lead? 
I still work with version 7.0.6.1 and sometimes it does happens, probably now could be the time to migrate  

Thanks
