Problem with manifest
 

When updating I got the following error:

Error Opening Manifest File: System.Data
bei System.Data.DataTable..ctor()
bei System.Data.DataTable..ctor(String tableName)
bei System.Data.XSDSchema.InstantiateTable(XmlSchemaElement node, XmlSchemaComplexType typeNode, Boolean isRef)
bei System.Data.XSDSchema.HandleTable(XmlSchemaElement node)
bei System.Data.XSDSchema.HandleDataSet(XmlSchemaElement node, Boolean isNewDataSet)
bei System.Data.XSDSchema.LoadSchema(XmlSchemaSet schemaSet, DataSet ds)

anyone an idea?

Have you tryed to press the update button again ?

I am also getting Manifest error while using updater version 1.2.10. The following error is displayed on the Updater screen:

Checking for new Manifest
Failed to download Manifest
Unknown downloading Error:
Manifest
The magic number in GZip header is not correct. Make sure you are passing in a GZip stream.

I have tried clean install of the updated and deleting the EQ2Map folder from UI and repatching again but still getting same error

The Manifest is only used in the updater , by the error it seems to be corrupted. If you press Update it will try again.

It works fine here so somehow it gets corrupted on your end, have no clue why :(
