Hi Wayne, Got a funny error opening one of my converted projects. Got a pop up windows that reads, Cannot add child - key already in use: ccp.molecule.ChemComp.StdChemComp"<memops.Implementation.MemopsRoodId: 79065008>:('DNA'.'U') This also came up in the terminal window. >>> Error loading file for: <ccp.molecule.ChemComp.StdChemComp ['DNA', 'U']> Reading: <open file '/Applications/ccpnmr/ccpnmr2.0/data/ccp/molecule/ ChemComp/DNA+U+msd_ccpnRef_2007-12-11-10-13-17_00008.xml', mode 'r' at 0x49c13c8> Last xml tag read: CHEM.ChemComp.chemAtomSets Parser state was: handling version compatibility Object stack was empty Error during Exo link dereferencing.
