Adapter losing connection with modules

[polfus]

Hey,
I own a orginal UCDS,
last days i have a problem about reading/writing modules. I'm using adapter for few minutes, im doing some changes, and then it just stops working. On every laptop, also on every car. It can't read any modules or overwrite them, the adapter is in can-mode. There's "Diagnostic error 00x0" in every module. I tried reinstalling software also.
Can you give me a solution for that? Thanks
