Parts and Dimensions not Displaying

I just reinstalled Solidworks after taking a couple year hiatus (I had uninstalled it in the meanwhile to free up space on my computer). After a long battle to even get the software installed and running, I'm now finding the solid parts don't display at all unless you mouse over them. I've tried all the different display styles with no success and I've checked the document display settings, but nothing looks incorrect and nothing is working. Dimensions have the same issue where they won't display the numbers as usual. I've never had this issue with Solidworks before and appreciate any suggestions. While I've used Solidworks for years and typically sing its praises, I'm beyond frustration this time around as I've spent several hours today trying to get the software installed and running, and now that I do, it's more or less unusable. I'm not sure what I'm missing. Thanks for your help!
