Could not obtain License

Hello all,

Running SolidWorks Premium 2011 SP5.0

Would like to utilise Photo view 360 however, when I try to load it I get the following message.

“Could not obtain license for Photo view 360

License server does not support this feature.

(-18, 147, 0)”

What does this mean and how can I activate Photo view 360?
