Issue opening file in 7.0 m050 works in 6.1 m090 after Sma to tia conversion

We have converted from SMA to TIA. If I open a file in 6.1 m090 it works fine. If the users open it in 7.0 m050 I get a parser error. There is no such element as 'title'. It also lists techinfoDomain.xsd as the file it cannot find a bunch of stuff in. Why would it work in 6.1 and not 7.0. From looking at the help session it looks like they are using the same file locations.

Thanks

Bryon
