When I try to run task using my Ni-DAQ Ver 6.9.3 and VI Logger Ver 1.0.1 on PCI

[AutoSafety]

Sometimes when I run task to capture data I get a messege " VI Logger Exectution Error - Could not start task: Logging Task"

When I reload VI Logger 1.0.1 and NI-DAQ 6.9.3 for Windows XP that fixes the problem, but not any more.

What shall I do?
