This is the error we get.
Method 'get_Lookups' in type 'Sitecore.Analytics.Data.DataAccess.MongoDb.MongoDbDataAdapterProvider' from assembly 'Sitecore.Analytics.MongoDB, Version=10.0.0.0, Culture=neutral, PublicKeyToken=null' does not have an implementation.
This happened after 7.5 upgrade to 8.2.3. Upgrade went well and website works, now when we try to enable analytics in Sitecore.Xdb.config. and then this error.
