If want to run VMRC directly, try:
"c:\Program Files (x86)\Common Files\VMware\VMware VMRC Plug-in\Internet Explorer\vmware-vmrc.exe" -h Steelhead:8333 "[standard] 1/rsp.vmx"
You would replace "1" with the slot name/number of your VM.
You should be prompted to login and then see the console if everything is working.
I assume the VM is running. Is it new? If not, can you RDP to it?
If things are in a weird state, I'd suggest disabling the slot, and then restarting the RSP service. Start the slot again and try to connect.
If that doesn't work then you'll probably want to open support case.
