Hi all,<br><br>Everytime I run macro files, I have this message:<br><br><span style="font-size: 10pt;">I/O warning : failed to load
external entity "Materials.xml"</span>
<p class="MsoNormal"><span style="font-size: 10pt;"><span style=""> </span>GateMaterialDatabase: did not find the
Materials.xml file: no properties read for material 'Air'</span></p><p class="MsoNormal"></p>Same message with other materials I use: Lead, NaI, Glass and Water.<br><br><br>Even if I run benchmark macros, I have same message, but the benchmark seem to run allright.
<br><br>What have I done wrong? <br><br><br>Thanks for your reply,<br>S<br><br>
