Thanks for posting in the Community. I'm sorry to hear you're having trouble with this. As a first step, could you please try opening Lucidchart in an Incognito Chrome window to help us narrow down the potential cause? Could you also try connecting to a different network? Sometimes account performance issues can be related to internet security/speed or browser issues. If you're still unable to open your documents after attempting these steps, please contact us here and include the following:
