Hello, and thanks for asking your question. My name is Bernie and I will be your expert today.
The Starter software you can use as long as you need, it's not on a trial or anything.
Lets try 2 things:1.
Since this started happening fairly recently, as a first step, lets try this, Click the Windows Start button > All Programs > Accessories > System Tools > System Restore
Follow the prompts to pick a restore date and time before your issue occured. You may need to check the show more restore points box to see more dates to pick. You will not lose any files, see if that works.2.
If not, then there is a tool that will take the Word registry back to it's defaults. This doesn't affect your files, please click HERE
Scroll down until you see the FixIt button, and click that > Download the Fixit file, then open and run it, and follow the prompts it gives you
After it's done, restart word and see if works now.
Let me know if that clears it up, if not, we will try some other steps
