S1 TOPS Coregistration "Cannot Create Data Buffer"

Hello S1 people: I am trying to coregister two imags following the tutorial of ESA and while it runs it says that it cannot create databuffer and it stops. Why is this happening? what should I do to solve it? I have a Windows 10, 8GB memory. and the version 4.0.0 of SNAP. I have done somethinf under tools-options where I checked an option about saving memory, as I read it in another post. However, the problem persist. Thank you.
