Hello, a former lurker here. I have been using the old Cakewalk Guitar Pro 2 for about a year and have had some success & some failures, but definitely learning. I recently bought some KRK monitors and went back to some older projects. After doing some tweaks, I tried to do another mixdown only to have the message abort mixdown pop up. Has anyone had this happen? Is there a fix? Also one last question, is there a way to import an old project that is in MP3 format now. I had to delete the original project due to lack of RAM. I've since added RAM and an external hard drive. Thanks!
