Hey there acagwinsc,
Welcome to the Community. I'm happy to offer my assistance to keep your account from freezing up.
I first recommend clearing the cache within Internet Explorer, which connects to your Desktop account. The cache can become bogged down with excess data, therefore slowing down the system. Steps on the clearing process can be found here: https://community.intuit.com/articles/1145697-how-do-i-clear-the-temporary-internet-files-and-cache.
Additionally, you may want to consider rebuilding and verifying your data in case there's any damage. More information on doing so can be found in this article: https://community.intuit.com/articles/1501314-resolve-data-damage-on-your-company-file.
This will get you back up and running. Keep up the great work and please let me know if you have any other questions.
