Corrupted pom.xml file

I started SpringSource, and clicked in 'create roo project' link; selected PizzaShop .roo file and used script command in roo to create the PizzaShop project. The project creates all the entities and looks fine. But after I try to reload it next day, using the 'select existing pom.xml file', SpringSource will show the project in red, saying that it can not be loaded.
I had not changed anything in the pom.xml file, so it does not let me work with the project anymore. Has anyone run into this problem before?
Any help would be extremely appreciated. I am running SpringSource in the Apple OSX Lion operating system, all the paths to Java SDK, roo, maven and tomcat are working fine. The SpringSource IDE does not provide feedback as to what is wrong with the pom file.

Please help me with this, since I was counting on roo to let me design web sites faster than following the standard path. On the other hand, if there is anything that I can do to help please let me know.

Man Thanks
