Why am I getting a NullPointerException?

I'm having trouble identifying an error that tells me there are no obvious errors and to look at the log. All of my data is either integer or binominal. Everyone else in my class was able to use the data, whereas I encountered this problem. I'm on version 10.2. 

Here's the log:

SEVERE: Process failed: operator cannot be executed. Check the log messages...

SEVERE: Here: 

SEVERE:           Process[1] (Process)

SEVERE:            subprocess 'Main Process'

SEVERE:              +- Retrieve EastWestAirlinesNN+_1_-1[1] (Retrieve)

SEVERE:        ==>   +- Cross Validation[1] (Cross Validation)

SEVERE:            subprocess 'Training'

SEVERE:                 |  +- Replace Missing Values[0] (Replace Missing Values)

SEVERE:                 |  +- Neural Net[0] (Neural Net)

SEVERE:            subprocess 'Testing'

SEVERE:                    +- Apply Model[0] (Apply Model)

SEVERE:                    +- Performance (2)[0] (Performance (Binominal Classification))

SEVERE: java.lang.NullPointerException

    Hi, Can you try the process again with having the replace missing values operator outside the cross validation? this worked for me.
