Hello Hemalath,
Please note that for urgent issues where CA Support can assist, you may be best off logging a Support issue, and/or using the "Chat" option that comes up when you start that process for Service Desk Manager. That way you may be able to reach out directly to an engineer, who can then speak with you and being a remote session if needed.
Your load command looks right for updating records. But for new records you may want to consider "pdm_load" with the "-i" switch.
Use "-c" to "check" what will happen. Maybe don't use the "-a" command.
And try all of this on a test system first, of course!
C:\PROGRA~2\CA\SERVIC~1\site\temp>pdm_userload /?
An input file name parameter must be entered
usage: pdm_userload -f [filename | -]
[-a (update all matching data)]
[-c (check only, no change to data)]
[-e (treat escapes literally)]
[-h (help)]
[-m (notify domsrvr of mass update)]
[-v (verbose)]
[-r (remove) | -u (update only)]
[-x (use locale sensitive numeric input formats)]

You haven't covered off a bit of information?
* You don't get your load to occur. But what happens? Error message? Log file update? Hang?
* What are you uploading? All fields? Some fields? Fields that already have similar values? A sample of the .DAT that you are uploading may help.
* Try using "-v" which will write verbose information to the logs.
* How is this scenario different to your prior working scenario?
Thanks, Kyle_R.
