I haven't seen that error before. Could you try to update to the latest nRFgo Studio and nRF51-Tools? Found here.
Does it work with nrfjprog? Run a cmd.exe and try nrfjprog --recover. Select the Segger serial number that corresponds to your kit.
im using nRFgo Studio v1.17
still problem remains after doing recover alsoo
Try to uninstall the J-link drivers in Device Manager (under USB controllers), unplug the board and plug it back in.
i had tried that too
am having two nRF51822 EK boards and this problem is only with one of them. the same gets connected sometimes and can be programmed and shows these problems ..........................................................................................................................
