Just ran into this problem today. I am assuming that it has something to do with the windows updates that installed last night, however i did a rollback but the update to ms security essentials is not removable. My problem at the moment seems to be a bit more severe... SolidWorks will crash whenever adding a hole table from ANY template. The only way I can can add a table now is by leaving the template selection box empty then reformatting the table on every drawing. I am going to the the full bug report through SolidWorks Rx so we'll see if anything ever gets done about this....
If I open a drawing with the table already placed then everything is ok as long as I dont have to remove/replace the table. I have tested this with new parts drawn from scratch just to be sure there wasnt a glitch with part translations, SW crashes everytime regardless of the part.
EDIT: Did some further testing and found that the crash is caused by using templates that combine tags (letters adn numbers). I can successflully add tables from combined sizes and standard templates... but whenever i use a template that combines tags, either default or custom, SW dies.
