This may be a driver issue. It was for me.

Go to your control panel.

>Hardware and Sound

>Devices and Printers

>Double click on your device

>Click Hardware

>Scroll until you find your GPU, Then double click it

>A window will pop-up. Click Change Settings

>Another Window will pop-up. Select Driver

>Click Roll Back Driver.

The program will freeze for a minute or two. Next you screen will switch off and then back on. Once the window is unfrozen click OK. You should now be able to open the mod-packs, but I recommend you reboot first.
