SharePoint 2013 Fund. Edition Search Service application fails

Currently have a Windows 2012 R2 server running SP 2013 Fundamental Edition.  A user reported that the documents uploaded a couple of days ago weren't showing up in the search results.  I decided to do the search on my PC and received the same results.  After logging into the SP server, I went to Central Administration > Manage service applications > Search Service Application and select any of the options under "Diagnostics" or "Crawling" "Queries", I receive this error:

The search application '2e5277af-19d2-441a-953e-2552fcbf1388' on server SHARE01 did not finish loading. View the event logs on the affected server for more information.

I've done some reading on the error but I'd rather ask the pro's what the best course of action is before I set off on my own expedition.  Thanks in advance for your time!

*update- I found that there is a command that you can run on each server in the farm (we only have one server) that will reset the permissions:

sconfig -cmd secureresources

Select allOpen in new window

Does anyone have any experience running this command or the follow up command?

psconfig -cmd upgrade

Select allOpen in new window

I don't mind running the commands but I don't want to wipe out the SharePoint content and settings that exist.  In other words, will those commands clear data, content, etc from our server or does it just reset the permissions?
