I have one vxdiag vcx nano gm cable and when running GDS2 software, I get error “no valid lease found” .
I tried to reset the computer date to China date, uninstall anti-virus program, reinstall GDS2 software, all the same results.
Possible reason and solution:
You may start GDS2 software from VX Manager, please run GDS2 from patch directly.
