I'm learning E+ and bcvtb (mle+) and when I run the example it has an error:

** Severe  ** ExternalInterface: Socket communication received error value " 1" at time = 0.10 hours.
**   ~~~   ** ExternalInterface: Flag from server " 1".
**  Fatal  ** Error in ExternalInterface: Check EnergyPlus *.err file.

while in Matlab it shows:

Reference to non-existent field 'Shade_Status_Off'.

Error in control_file_blind_angle (line 36)
        ShadeStatus = userdata.Shade_Status_Off;

Error in mlepRunTemplateSysID (line 157)
        [inputStruct, mlep.data.userdata] = feval(mlep.data.funcHandle, cmd, mlepOut, mlepIn, time(1:kStep), kStep,
        mlep.data.userdata); %.data.userdata NEED TO CHANGE,eplusOutPrev, eplusInPrev, time
Error in mlepSimulateFunction>runSimulation (line 43)
[data.time data.input data.output mlep] = mlepRunTemplateSysID(mlep);

Error in mlepSimulateFunction (line 10)
    [mlep] = runSimulation(mlep);

Error while evaluating uicontrol Callback

I use the newest E+ version, also tried the previous v.8.00 version, which had the same problem.

I found an answer in previous question which gave a link but can not use now: https://corbu.lbl.gov/svn/fmu/EnergyP...

I don't know how to fix it, and why the field 'Shade_Status_Off' does not exist? it is in the userData.mat
