When I go File->Open Saved Optimization File

I get "Exception loading Saved Optimization: Strategy Parameters are mismatched"

I am not aware of any changes to the strategy or its parameters.

What went wrong?
What can I do?
Any chance to rectify the situation?

This was an expensive optimization run and I'd like to review its results.

... or - to be more specific:

What are the exact conditions for a Saved Optimization file to be reloadable?

Could you send the file to support@wealth-lab.com?

I resolved this problem. What happened?
I made "Knife Juggler" optimizable by creating start, end and step values for its three parameters.
Run an optimization and saved the optimization results.
Then I upgraded WL 8 to Build 20.
This obviously restored Sample Strategies/Knife Juggler to a strategy without optimizable parameters.
After making all three parameters of Knife Juggler optimizable again, I could load my Saved Optimizations file without any problems.

I didn't know that an upgrade restores the Sample Strategies (and reverts all changes without further notice).

[Feature Request:] Probably some warning message will avoid future trouble...

What is missing in your description is that you probably deleted the WL8 user data folder. Because the names of copied strategies are cached there in Settings.txt. Otherwise the strategy would not get overwritten.
