BVAR error

[Chopin37]

Hello,

I am trying to estimate a 6-variate 2 lags BVAR with the Sims-Zha Normal-Wishart diagonal prior with standard hyperparameters in EViews 8 (mu5=1, mu6=1, all else as default) but when I try to include a sixth variable I get the familiar error message “positive or non-negative argument to function expected”.
I am quite new to EViews and BVARs so I was hoping I could get some help with solving this problem. It would be terribly appreciated.
The workfile is attached.

Thank you very much.
