qiskit: credentials failed for qiskit ver 0.6.1

Informations

• Qiskit Terra version: 0.6.1
• Python version: 3.7.0
• Operating system:MAC OSX 10.13.6

What is the current behavior?

After I acquired fresh token from https://quantumexperience.ng.bluemix.net/qx/account/advanced IBMQ.load_accounts() fails.

Steps to reproduce the problem

from qiskit import IBMQ
myToken='b6abe11442c9a...'
IBMQ.save_account(myToken)
IBMQ.load_accounts()

Results with

Traceback (most recent call last):
  File "/anaconda3/lib/python3.7/site-packages/qiskit/backends/ibmq/ibmqsingleprovider.py", line 71, in _authenticate
    credentials.verify)

    raise CredentialsError('error during login: %s' % error_message)
IBMQuantumExperience.IBMQuantumExperience.CredentialsError: error during login: Wrong user or password, check your credentials.

What is the expected behavior?

Would be better if IBMQ.load_accounts() accepted me. All worked well w/ ver 0.5.
