Try navigating to your WL7 User Data folder, it should be in a path like ...

C:\Users\{your user name}\AppData\Roaming\WealthLab7

... and look for a file named PersistedOrders.txt. Does it exist? If so, delete it and try restarting and report back the results.

Thanks for the report, still trying to work through the cause, but WL7 will handle this exception for the next build so it won't prevent it from starting up.

Haven't you already started a new topic for your issue?

At the risk of repeating, I explained that you're still using WL7 B53 (I just double checked this a few moments ago) but this issue is resolved in WL8.
