I have searched the forum and found others with this problem but no answers. I set task scheduler to convert one drawing file into pdf. It opens SW properly and then the progress window just spins. ( I've let it spin for 30 min. I've used task scheduler before and it usually resonds very quickly.) I found it behaves the same for a set of 14 drawigns, changed which drawing is first on the list, tried different options like printing to pdf, creating edrawings, they just all sit and spin on the first part. I tried rebooting, no luck. Anyone have some ideas?
