I was testing out dynamic data set in a backtest and accidentally clicked back on the dynamic dataset window and it crashed WL7. I cannot re-open WL7 without getting the same error code now.
It gave the following error code:
System.Windows.Markup.XamlParseException: The invocation of the constructor on type 'WealthLab7.MainWindow' that matches the specified binding constraints threw an exception.
---> System.FormatException: Input string was not in a correct format.

I asked Eugene to look into this, but for now you could try deleting any "Scanner" entry from your Settings.txt file, the file is located here:
C:\Users\{UserName}\AppData\Roaming\WealthLab7
C:\Users\{UserName}\AppData\Roaming\WealthLab7
That allowed me to re-open WL7! thanks!
I saved and rebuilt the dynamic DataSet while backtesting several times, effectively changing its composition. This did not crash WL7 for me. Please copy/paste all the Scanner* entries from your Settings.txt file if it crashes on you again for my troubleshooting.
Will do if it happens again
I receive the following message at every start up of WL7.

I deleted the scanner settings in the text file again and I was able to open WL7 again. Below are the settings from my Settings text file for the scanner that was crashing WL7 and preventing it from opening

Fixed in upcoming build 13 of the DataExtensions. Thanks.
So as not to delete the whole block of settings, these are the offending lines until the fix:
QUOTE:
ScannerPriceGreaterThan=0.5
ScannerPriceLessThan=5
Fixed, please update Data Extensions to build 12:
