The source was&nbsp;coming from the part list.xml.&nbsp;Everytime we renamed a part list in the main style library the error that you were talking about appeares. Its like you say, the only way was, for us, to go search&nbsp;for a Backup of that style and replace&nbsp;it with the old one.If you want to rename a&nbsp;part list.&nbsp;I heard that, its only possible to change&nbsp;it by&nbsp;going trough&nbsp;the style library manager.</P><P>&nbsp;</P><P>Good news i think. I did not confirmed it myself. But i heard that inventor 2015 fixed that problem.</P><P>&nbsp;</P><P>Sorry, for the bad english (not my first language)</P><P>&nbsp;</P><P>Hope you can fix soon your problem.</P> Fri, 13 Mar 2015 15:12:53 GMT DanielCTurcotte 2015-03-13T15:12:53Z
