Hi Casper,
the problem with the splines is, that they are not backward compatible. There is a solution however.
1. Open for edit the spline you want to downgrade.
2. Pick out the config.txt and make a copy of it (under the name config2004.txt, for example)
3. Open for edit another spline object, which is error free under TRS2004.
4. Check and compare the error free config.txt of the TRS2004 version to that of TS2009.
5. Try to reproduce in the config2004.txt all differences you observe compared to that of the functional 2004 spline-config
6. When finished save your config2004.txt as config.txt (before this it is recommended to save the original config.txt as originalconfig.txt in case of accidents

)
Put the model in the TRS2004.
Be aware of, that this method needs probaly more trials until you succed, but i tested it and it works fine.
