I've been using an SNL for years with no problems on SW2013. I temporarily installed a standalone copy of SW2015 to open a customer file(we are not on subscription right now). After uninstalling SW2015, I could not pull a network license on SW2013, so I did a complete clean install. Deleted all SW files and registry items. Now I get the "Solidworks licenses will expire in 30 days message" on startup unless I go into the SNL Manager and manually borrow a license. Solidworks will not pull the license automatically. I really don't want to have to borrow a license every 30 days.
