Hi oporras,
Please don't include spaces or special characters in vSphere names (usernames, datacenters, clusters, etc.). You can see this is in the VMmark User's Guide under "Configure vCenter Server".
Once you have fixed that, if you are still having a problem, please zip the VMmark results folder and upload it as an attachment to this forum thread. This will help me troubleshoot the issue.
Thank you,
Rebecca
