Hi, guyz

i have installed Virtual brick software successfully to my (Windows 8.1) machine. Then, i had activated the license and i received a windows pop up shows activated. During the virtual brick program launching, i received error message in the notepad showing:



NativeException (0x80004005): Error 259: No more data is available
at ?A0xe9568384.open_dev_node()
at USB.Interface..ctor(_USB_DEVICE_DESCRIPTOR* desc, _USB_CONFIGURATION_DESCRIPTOR* config, _USB_INTERFACE_DESCRIPTOR* uinf, _USB_ENDPOINT_DESCRIPTOR* endpoints, _USB_STRING_DESCRIPTOR** strings, UInt64 numStrings)
at HostComm.Init()
at Program.Main(String[] args)


and it wont launching.

I got solution from support@robotc.net. Its simple.. Tried these two method. and it works

1.
In this case, I suggest reinstalling the Virtual USB Driver, as this issue usually appears when the driver is not installed properly during the Virtual Brick installation. To install the Virtual USB driver:

Log into an administrator's account on the computer
Navigate to the Virtual Brick installation directory (C:\Program Files (x86)\RVW Virtual Brick)
Right click on the NXTDriver.bat install batch file
Select the 'Run as Administrator' option to launch the driver installer

This should reinstall the driver for you automatically and resolve this issue.

2. Just Reinstall Virtual Brick250 and restart the machine.
