Help: Cannot log into vRO Client

Hello,

I am not sure what the issue is today but I cannot log into the vRO client. There haven't been any configuration changes that I know of and I know that my account is not locked out. The error I am getting is Invalid username/password. I thought this indicated a version mismatch and so I downloaded the most recent version of vRO that is recommended on my configuration page: vRealizeOrchestratorClient-64bit-6.0.1.exe  Windows 64-bit. Has anyone seen this before or does anyone how how to resolve it?

thanks,
