I use GUIMiner to mine bitcoins using my graphics card, and in a pool. I've upgraded to Windows 8 this morning, but now GUIMiner won't launch!
All I get is the icon in the taskbar for a few seconds, and it disapears. I have no error message, no windows, and no error logs.
I have tried launching the application as an administrator, and in "Windows XP" and "Windows 7" compatibility modes.
How can I fix this problem?
