Code: err:winedevice:ServiceMain driver L"sptd" failed to load It means Wine tried to load a driver called sptd.sys and couldn't. According to Google, sptd.sys is a driver installed by Daemon Tools and Alcohol 120%, and is supposed to load at boot. That means Wine is going to try to load it whenever you try to start anything in that particular wineprefix (even winecfg). Apparently it causes a lot of problems in Windows, too. My guess is that the slowness is caused by Wine's attempting to load this driver.
