Error reading user-defined type from file

Hi,  

I'm trying to read a user-defined class back from file. The object is of type SimulationInfoBlockVector, which internally has an std::SimulationInfoBlock:  

I get the following error message:  

SimulationInfoBlockVector* p_vec;

root [9] p_vec = (SimulationInfoBlockVector*)p_file->Get("blockvector");

Error in <TBufferFile::ReadVersion>: Could not find the StreamerInfo with a checksum of 81920 for the class "vector<SimulationInfoBlock>" in simulationorganizersmalldirect.root.  

Is there an indication as to what might be wrong here?  

Thanks,

Marc
