Client app started spazzing out after update


I had a company(old) and company-secured(updated). I renames company-secured to company and disable company(old) to launch an update.

The system was working fine, but towards the end of the work day started freezing up, and even not showing the navigation, locking out users on a specific page.

Where can I look to see what happend. The logs looked fine to me. I dont know if the system overloaded. maybe the computers running the client didnt meet specs. I’m really lost.

Any help would greatly be appreciated!

Thank you in advance.
