The link to the first article is broken, taking me to a page that says "Accounting Help has moved," and directing me to another search page.  Will you re-share that article?  I tried searching for the error I'm getting "Please wait while we launch lacerte" but this appears to be the only relevant post anywhere in the top of my search results, so I'm not seeing the original article you're referencing.

2018 is the only Lacerte software giving me this problem.  I have tried rebooting, and reinstalling 2018 (with a subsequent req'd reboot).  No success, so I'm curious what other steps there might be.
