Sorry... here is a complete log. What bugs me is that it did work well. Burned something in the AM and next time I went to use it the same day, it failed. There are 2 burners in the system. Same results from each. I 13:53:04 ImgBurn Version 2.5.0.0 started!

Looking for a little help with this one. Errors are: W 22:41:24 DeviceIoControl(IOCTL_STORAGE_MCN_CONTROL) Failed! - Media change notification has NOT been disabled. W 22:41:35 DeviceIoControl(IOCTL_CDROM_EXCLUSIVE_ACCESS, Lock, 1) Failed! - Reason: The handle is invalid. Was getting "device busy / inuse by Nobody" errors from another burn engine. Imgburn is letting me get around those errors but reporting a couple of issues as I mention above. Tried to search for processes that might have devices tied up in process explorer - none, tried removing devices in device mgr and rebooting, unlocker tells me that no locking handle found.
