Hello, dear WL team,

I installed WL9 with the available extensions for WL9 and performed the migration from WL8. I can start WL9, but when I try to access a Building Block strategy, this error message appears at the bottom of the screen:

"Trade History Manager: Exception Initializing Trade History: The input string 'CASY' was not in a correct format."

The strategy doesn't load.

I also can't access the "Preferences"; nothing is displayed.

WL8 won't start after the migration either. Therefore, I won't be able to trade my strategies tomorrow.

What can I do?

Thank you very much!

We don't understand how the migration could have possible affected WL8, but to get running again, try renaming the Settings.txt file in the User Data folder:
C:\Users\[you]\AppData\Roaming\WealthLab8\Settings.txt

Rename it to something like SettingsOld.txt, and then try starting WL8. If it works (and if you don't have a backup for Settings.txt), you'll need to go through all your Preferences. If you want, send us the SettingsOld.txt file and maybe it can be repaired.
