Errors-duplicate-wealthlab-settings-on-a-2nd-computer

I copied all user data folder files from working WB on main computer to 2nd one. All data and settings are the same on both machines but I get the following errors when opening a new chart on 2nd unit.

I tried to update data as there is none, did not work got error: IQfeed disconnected, Could not load type 'WealthLab.Core.Out' from assembly 'WealthLab.Core, Version=8.0.1.0, Culture=neutral, PublicKeyToken=null'.

Can someone help me correct this? Thanks. John
