Strategy error in Beta 12...

[funk101]

I just installed the new Beta 12 -> 8.0.0.12 64-bit (Multi-Broker) - BETA and BAM! I get this error. I have NO strategies. Why would I get this?
(See attached screenshot)

Try removing your workspace.xml file.

If you mean -> * _Workspaces.xml*, that did not work for me

I got the same error after installing B12 on top of B11:
2016-07-17 23:53:00:389|3|4|Strategy '73528371': unable to deserialize user data: There is an error in XML document (56, 4).

Removing all xml workspaces from Documents\NinjaTrader 8\workspaces didn't resolve the issue.

Thanks

Hello,
I have not encountered this after installing Beta 11 on top of Beta 12. Are there any other steps you took when transitioning from Beta 11 to Beta 12? Did you receive any errors with the installation?

Also, can you send me your log and trace files so I may review them further?
You can do this by going to the Control Center-> Help-> Mail to Platform Support.

Ensuring 'Log and Trace Files' is checked will include these files. This is checked by default.

Please reference the following ticket number in the body of the email: 1544888

Thanks for looking into it.

I just sent a log.

I didn't get any errors during installation. Now I am getting this error in the log every time I start NinjaTrader.

Thanks

Resetting database worked for me.

Found in http://ninjatrader.com/support/forum...ad.php?t=43270

Removing templates/strategies didn't fix the issue but resetting DB did help.

Thanks
