So, I installed Mathematica 10 the other day alongside 9 and let it remove Mathematica 8. While it was installing, I briefly saw a message about Mathematica 9 Extras being removed. At the time, I didn't think much about it as I assumed that 9 would still continue to be able to use the Extras from 10.
I'm not sure if FinancialData is one of the Extras, or not, but it is no longer working in 9. If I try something simple like:
I just get $Failed. Of course, that works just fine in 10. Is there any way to recover this functionality in 9 while still keeping 10 installed?
