How do I fix my tablet being stuck on startup screen?

My tagital TX7 will turn on and startup, but it gets stuck on part of the startup screen "TABLET PC Keep Moving Forward" and will not progress any further than that. I can cut it off, force reboot it, run it until dead then recharge to full, but it won't progress past this startup screen. I don't want to factor reset it because there is some information and files in apps on the tablet that I want to access and was in the process of manually copying typing onto another device when all this started,,
