Hi all How can I go back to build 1326 every since we installed new build had all kinds of trouble, Slice planar taking one hour to comput toolpath, remove geometry crash, have been on the phone with tech help they say the problem with slice planar is from the people that made the software. I have a hp pavilion dv7-1245 dx laptop with a amd turion x2 dual-core processor, ati radeon hd 3200 graphic card 4 gig of memory and 225 gb of free space. Every thing worked great till the last two builds last week, I need to get back up and running I have lost five days of production. Please help Thank You
