Hi,
please check and see if you are running robot 7.80, if not try upgrading to that.
also check and see if their is any antivirus on that system scanning the nimsoft directory.
If that does not help you will probably need to contact support to have them help find the problem with the environment.
There used to be an issue with this prior to 3.22 version of the probe.
if you have not tried completed deleting the probe and reinstalling it that is another thing to try.
hope this helps
