Hello,

What you think is a clue is misleading. You updated Wealth-Lab to the actual build in February or March so it definitely doesn't have to do with this. Neither is the Quandl provider the source of error, despite its presence in the stack trace: no updates to the extension in a year.

Scroll down to Errors | Strategy > "Runtime error: Attempting to Deserialize an empty stream." That is how the error translates to English. You'll find two suggestions there (GetExternalSymbol and "Benchmark Buy & Hold"), please give a try to both.
