This has just started happening. When I click on the icon to start Barca, it begins to start, and then disappears. When I have task manager running, I see it briefly appear in the list and then disappear. No error message. Nothing. I tried reinstalling Barca without success. It helped for a day or so and then began doing this again.
Update: I decided to try the instructions in another post about changing the compatibility choices and it worked, though I had to use the compatibility option for Windows NT (Service Pack 5) because there were no compatibility options for Windows XP at all. I'm not sure why this works but am glad it does.
