Correct Georeference of Shapefile?

i hope this is the right Subforum for my problem:

I had a topographic thematic map as a tiff file, but without any spatial reference. So i referenced it with Erdas Imagine using Bing Maps as a reference. After that i vectorised some parts of the map by drawing it and save it as a shapefile. I used the Project Feature and Projekt Raster Tool (Data Management) in Arcmap 10.0 to transform the shapes as well as the rastermap in an UTM wgs 84 coordinate system. Now they overlap each other as how it should be, but when i load them into an Arcmap Project with other Datasets, they don`t overlap with those like they should. Instead, they have a shift of about 2000 km in north east direction.

How can that be? It must be something about the transformation of the projection, because the referenciation can´t be that bad. Has anyone an idea for a solution?

ps: sry for english mistakes.
