Can I please have some assistance in resolving this issue? the add on files are already present in the folder.. I had 2 add ons missing earlier- the 'Mep Modeler' and the 'Interactive Schedule'. I downloaded the 'add on folder' all over again, that resolved the- 'missing Mep Modeler add on' but the Interactive Schedule add on is still there.. I also tried turning off the firewall, but didn't work..
