I appreciate you for performing some steps, JETIA.

I understand how it feels when you've been circling around to resolve the encountered issue. We want to ensure you have a better experience than this. Thus, I'm here to provide all the necessary information to rectify your concerns.

Since you mentioned that you've been using QuickBooks since 2004, I'll take that you're using the old version of the software. If so, this might be the reason why you're unable to switch between companies. An outdated one won't receive product updates that fix data-related issues. 

You might want to upgrade your QuickBooks Desktop software to receive the latest critical security patches and updates. We will begin by opening and upgrading your file to the 2007 version, then proceed to 2010, 2013, 2016, 2019, and finally to either 2022 or 2023. After opening the file in each version, remember to create a backup copy and restore it to the next version, until you can successfully restore and open it in either QuickBooks 2022 or 2023.

If you feel uncomfortable doing these steps, you can contact our customer support so an agent can guide you through the process.

Keep me posted whenever you have concerns about your QuickBooks file.
