I would think that there must be some problem with the Excel spreadsheet.
Try copying the data to another spreadsheet and use that.

I am trying to mail merge labels using an Excel spreadsheet as the data
source, something I've done many times before. Now whenever I try, the
3-step
Mail Merge Helper dialogue box opens, and when I click on Step 2 to "Get
Data," it allows me to select the data source but then freezes up. I
cannot
get any further than this step. I have tried numerous times and it always
freezes and ends up saying "Not responding."
