I am having much difficulty downloading the 2014 SP2 Upgrade.  I have succesfully been able to upgrade the SNL module for our Simulation and Flow Simulation.  However the existing SW2013 users cannot add-in SNL's because of version mismatch.  I waiting on help with the SW2014 download but may be able to get the PDM upgrade. If I do... and I install while waiting for SW2014 SP2 download resolution... will I have the same problem?  In other words will all 2013 users be locked out of PDM Vault due to version mismatch?
