TDMS Error -2503 at Open TDMS

Hi everyone,

I'm facing a wierd error since yesterday.

I'm recording data on a PXI using the Embedded Data Logger Custom Device (VeriStand), before yesterday,

I was able to retrieve the TDMS File (.tdms file only, not the .tdms_index file) and open the file using TDMS File Viewer or DiaDEM.

But since yesterday, TDMS File Viewer returns me the following -2503 error (see picture below):

I noticed that this error occures only the first time I try to open the file, and that a .tdms_index file is created at the same time. Then, the next time I try to open the .tdms file, it works quite nice.

Does anyone knows about this error, and what's the reason ?

Thanks ...
