Alteryx Freezing

[Brook_G]

Good afternoon.  Recently my Alteryx workflows have been freezing up.  I get a 'not responding' message and then it closes.  Also, simple workflows with small input files are taking 10 minutes or more to run.  Any ideas on why this is happening? I looked at the profile processing time and it seems to be the input files that are taking up so much time.  In my current workflow I only have two input files and they're only 14 and 122 KB in size.

You may have already done this, but have you fully shut down your computer and restarted it in a while? Sometimes a clean reboot helps the computer work without those processes that take up memory and processing power.
