TDM Reading Waveform Length

Hello,
 
I do have a problem working with tdm files.
There is a very big number of tdm files (each has a size of ~1.4GB) that I want do analyse. Every file consists of 16 Channels. To  process the files without getting an out of memory error I want to read subsets of the files and therefore I need to know the waveform length of each channel. But even trying to read the waveformlength (VI Get Properties (Channel)) produces an out of memory error. I do not understand this, since reading just the length should only return an integer value.
 
What should I do?

Hello,

is the error also with small data files? Can you attach your VI please? With which version are you working?

Thanks,
