Train dataset for temp stage can not be filled. - opencv 2.4.8

edit

Here is my dir structure:

D:\opencv\....
D:\logo\...

I ran the following powershell scripts:

Get-ChildItem -Path ".\negative" | ForEach-Object -Process { "negative\" + $_.Name } | Out-File -FilePath "negative.txt"

..\opencv\build\x64\vc12\bin\opencv_createsamples.exe -vec "positive.vec" -img ".\positive\grayscale\grayscale-logo.jpg" -num 1000 -maxyangle .53 -maxxangle .53 -maxzangle .53 -w 44 -h 34

..\opencv\build\x64\vc12\bin\opencv_traincascade.exe -data "output" -vec "positive.vec" -bg "negative.txt" -numPos 1000 -numNeg 3019 -numStages 20 -w 44 -h 34

I have 3019 negative images in

D:\logo\negative\

I have a logo at

D:\positive\grayscale\grayscale-logo.jpg

I am getting the following error

Train dataset for temp stage can not be filled. Branch training terminated.
Cascade classifier can't be trained. Check the used training parameters.

What might be going on that I am getting that error? I installed OpenCV 2.4.8 on my Windows 8.1 box and used the binaries that were provided.
