Hi BKWIS,
Several thoughts here:
1) DIAdem 2014 was a 32bit application, so you are only using the first couple of GB of your available RAM for DIAdem data management. Subsequent DIAdem versions had the option of 64bit execution, and recent DIAdem versions are only 64bit. That's an all around better tool to use when dealing with very large data sets.
2) The maximum number of data channels that could be loaded in DIAdem 2014 is 2^16 -1 = 65535, the exact number you say is in this TDMS data file. If there's even 1 more channel in that TDMS file than you think, then a straight load attempt will fail for that reason. Recent DIAdem versions allow up to 150000 channels to be loaded at a time in DIAdem, so again that would be a better tool with data files like these.
3) DIAdem 2014 and indeed DIAdem 2020 also has a maximum channel length of 2^31 -1 = 2147483648 values per channel. If even one of the channels in your TDMS file is longer than this, then a straight load attempt will fail for that reason. Here newer DIAdem versions do not (yet) help.
4) Please try right-clicking on your TDMS file and choosing "Register Data" or "Data Reduction..." instead of "Load Data" or just dragging the TDMS data file into the Data Portal. Register loading or partial loading of your data file may succeed where straight (complete) loading fails. You have options to do any or all of this custom loading programmatically, as well. These options exist in DIAdem 2014 already.
5) The number of Groups is not a limitation, you can focus on other things and ignore that.
Are you able to try installing DIAdem 2020 in evaluation mode on a test computer to see if that helps? Otherwise, let us know what happens when you try 4) above.
