Hello Billy and welcome to Wikitree.
The problem you are likely encountering is due to your newness on this site. There is a limit on the first Gedcom you can import into the site which is about 25-50 people(I am not sure the exact limit).
This is to help you get used to how the site works.
Another issue may be how many people are actually in your Gedcom.
Look at the pages at https://www.wikitree.com/wiki/Category:GEDCOMs which may help you learn how wikitree handles Gedcoms and what needs to be done afterwards.
What I suggest is bring your tree here but in small easily manageable chunks so you don't get overwhelmed.
You will also get other people who will may make changes on the profiles you create. That is because We collaborate. When we share ancestors we work together on the same ancestor profiles.
