This is the response I got from Ross-Tech but I have not been able to change to 16-8-2-2 as I am missing RT-usb .dll so I am stuck any ideas? I believe we have a potential fix for this that we'd like you to try. Unfortunately it's a little more complicated than running a new installer but it shouldn't be too bad.
First, make a copy of your whole C:\Ross-Tech\VCDS\ folder and name it something else like:
C:\Ross-Tech\VCDS-1682\
Next, in the new folder, delete all of the files found here:
C:\Ross-Tech\VCDS-1682\UDS_EV\
There should be 5032 of them so this may take a while.
Next, save this file and open it open it with WinZip/WinRAR/7zip:
http://download.ross-tech.com/VCDS/download/tmp/DS260-0.rar
Save all of the files in there (should be 6248 of them) to the folder you emptied:
C:\Ross-Tech\VCDS-1682\UDS_EV\
Finally, save this file:
http://download.ross-tech.com/VCDS/download/tmp/VCDS-16-8-2-2-x86.zip
... and open it with WinZip/WinRAR/7zip and copy the enclosed VCDS.EXE file here (replacing the one that already exists):
C:\Ross-Tech\VCDS-1682\
Please try using that version (make sure it says Release 16.8.2) to view Adaptation values in your 09 module and let us know the results. We would appreciate an AutoScan. If you encounter problems, please go to Options and set Debug to 1024 then try reading one of the adaptation channels that's failing and send us the contents of the Debug folder.
Regards,
Andy
