Error when training a neural network with more than 1 dimension

I have a neural network license, and am able to execute the first two examples found in the Matlab documentation here: https://ch.mathworks.com/help/nnet/ref/train.html

These use the builtin 'maglev_dataset', which is 1 dimensional. However, the other examples using the 'vinyl_dataset', which has more than 1 dimension, all throw the following error immediately.

>> [x,t] = vinyl_dataset; 
>> net = fitnet([60 30]); 
>> net = train(net,x,t); 
Index exceeds matrix dimensions. 

Error in initnw>initialize_layer (line 168) 
range(inputStart(j):inputStop(j),:) = temp2((inputStart(j):inputStop(j))-inputStart(j)+1,:); 

Error in initnw (line 93) 
out1 = initialize_layer(in1,in2); 

Error in initlay>initialize_network (line 147) 
net = feval(initFcn,net,i); 

Error in initlay (line 89) 
out1 = initialize_network(in1); 

Error in network/init (line 32) 
net = feval(initFcn,net); 

Error in network/configure (line 246) 
net = init(net); 

Error in nntraining.config (line 116) 
net = configure(network(net),X,T); 

Error in nntraining.setup>setupPerWorker (line 68) 
[net,X,Xi,Ai,T,EW,Q,TS,err] = nntraining.config(net,X,Xi,Ai,T,EW,configNetEnable); 

Error in nntraining.setup (line 43) 
[net,data,tr,err] = setupPerWorker(net,trainFcn,X,Xi,Ai,T,EW,enableConfigure); 

Error in network/train (line 321) 
[net,data,tr,err] = nntraining.setup(net,net.trainFcn,X,Xi,Ai,T,EW,enableConfigure,isComposite);

What on earth is wrong? My colleagues who use the same license do not have this problem!

Could you try running restoredefaultpath, and check again?

Thank you! it was indeed a path issue, and I've reordered it accordingly.
