Can´t debug using Eclipse with nrf51_pca10028

IosuGorostiza <balcalde@...>

Hi everybody:
I´m trying to debug the sample hello_world with Eclipse Photon Release 4.8.0. in Windows 8.1 Enterprise 64bit. I followed every step  showed in the Eclipse Debbuging part of the Application Development Primer guide. Every step is ok but when I try to run de application I get the next error:

"Launching New_configuration has encountered a problem
Error in services launch sequence
Starting pyOCD GDB Server timed out."

I installed the pyOCD using "pip install --pre -U pyocd"

I apreciate every help, because I´m not able to find the origin of the problem.
Thanks in advance.
Best regards.
