I'm a student who is using PTC Creo 3.0 Student Edition, I have installed the software on my laptop since September of 2016, and it works great without no problem. But yesterday the software crashed and started works very slow, when I try to do a sketch or access the menus its works very slow. I think the problem is not in the computer's hardware, because the software works great until yesterday. I have others CAD and design programs on my computer and I've checked them, for make sure if I had a problem with the graphic card, and there isn't any problem with them. I have windows 10 and also all the drivers updates.
I have checked the forum before and I saw a similar post about it, it mentions about modify the config.pro file, I followed all the steps and tried it, but the program still have the same problem.
