VCDS cable CLONE work ONLY with the soft arrived with the cable. And the cable have inside the corresponding and necesary firmware.
Any another version of soft can destroy your cable.

IF your cable worked correctly with the soft arrived at the bought momment and now must update fw, you using a newer version (or by "curriosity" - "maybe work", or the pc has connected on internet at RT servers).

In both cases try to uninstall all versions of VCDS having and drivers for vcds cable, including from registry, restarting pc and reinstall. Must know what you do.

IF after that your cable work again, ok, if not, your cable must reprogramming.

That's all is correctly for clones...
For oem cable the update is free.

Usefull is if you tell us more details: version, few photos from inside...FW version, etc.
