I've tried everything so far. One weird thing is where I go to uninstall or repair the program all my other programs list a program size in mb or gb. ext to NCH it says size:unavailable. So i thought maybe didnt get everything in dl. dl'ed it a few more times and says the same. I can open videopad video editor which is part of the options with program dl. that works fine till I hit record and it sends me to debut and it instantly locks even from that start location. i turned off my anti virus thinking there was a conflict. i have a high end nvidia processor and like i said i have a topend labtop I bought a month ago. thus why i bought the program (and yes i know the free version would do the same things io need) but i have been using the program now for years and figured I should pay for this version on this machine. I even took a version I have on other p\c and tried that ( runs fine on that machine) wouldnt run on this one.
