Hello. I am using Autodesk inventor professional 2013 (student version) and whenever i press create 2D scetch or i press mouse wheel button it stops working (drops me a submit an error window). i tryed to reinstal it for many times and it started to work for a single time (when i close the program and start it again it stops working again). But afted some time reinstalling program did not helped anymore. Now I can't use my inventor. I also tryed to install updates but it didn't helped. I laptop is powerful enough to run a program. Did anybody had same problem? Please help me.
