Hello all. Hope someone can help. I am using Virtual Box Version 5.2.0 r118431 (Qt5.6.2). Yesterday it worked fine. Before I shut the VM down yesterday it asked to be updated. I allowed it to update and now I can't start Virtual Box again. When I try I get the following error message:

10.15,Mojave,Mavericks,10.12,10.13,黑苹果系统, Mac系统,iPhone交流，OS X Yosemite,苹果软件下载,黑苹果驱动,苹果游戏,无损音乐下载,高清电影. Realtek PCIe GBE Family Controller官方驱动下. Realtek PCIe FE Family Controller kext for High Sierra? Posted by 2 years ago. Realtek PCIe FE Family Controller kext for High Sierra? Realtek actually offered drivers for Mac OS X, for those older NICs, but that stuff is pretty ancient these days.

I am running Windows 10 Creators Edition as my host machine.
I saw someone else posted about this same issue on a Windows 8 machine in the past. That person was advised that the VM broke after the update and that they should right click on the Virtual Machine and then click 'Discard Saved State.'
When I right click on the Virtual Machine the option to 'Discard Saved State' is grayed out for me so I can't choose this option.
Is there a fix for this or do I just need to delete my virtual machine and reinstall it?
I've had problems with 5.2.0 and my network connections even before I let the update install yesterday. Before yesterday I could only use 5.2.0 with an Ethernet connection on my host machine. If I try to use my wireless adapter I can't get the VM to connect to the Internet. Now, since this update, the VM won't even start for me.
