Would this problem stop if I purchased an updated edition? Also, one of the files I want to work with is a 4.03 GB .mpg.
Feasibly speaking, should I have an easy go with this project with an updated program?
Thanks in advance.
I have no idea. You'll certainly be able to open the current project to continue working and you'll have many more producing options and features available to you, but I can't say for sure if that would solve the problems you're experiencing or not.
I say that mostly because it appears that you have some issues going on with Windows and also with a couple other programs you've installed, namely EZ Grabber and WinX_DVD_Ripper_Platinum. Problems with either of these programs might cause issues with PD and I suggest you uninstall both of them as the first diagnostic step. Make sure you reboot.
You may then want to reinstall PD12 (assuming you have the original installer CD). If you need a new copy, contact CL tech support as mentioned in the RMBP guide. Once that's done, make sure you update it to the final patch (build 4210) from
here.
If that works, think carefully about whether you need the 2 removed apps and then make sure you have the latest versions before installing them.
If the crash still exists, try the steps in bold in this
post to see if there's any damage to Windows core files that can be repaired.
Finally, I suggest you download and install what is likely the final driver for your Intel HD 4400 GPU from this
page.
Let us know what you find!
