Give us some more info here. What version of windows are you using? Are you using 2.00 of both emplode and the player software found here: http://www.empeg.com/cgi-bin/display.cgi?section=downloads&id=3

Regarding USB, this is from the release notes (at the link above):

Quote:
We recommend completely de-installing the previous emplode before
installing the new one.

The USB driver has been moved out of the emplode setup program since just
placing it in the drivers directory wasn't advisable on modern operating
systems. In order to improve reliability on Windows XP there is now a new
USB driver specifically for Windows XP called RIOXDRV.SYS. Users of
earlier operating systems (Windows 98, Windows 98SE, Windows ME and
Windows 2000) should continue to use the RIOHD.SYS driver. Anyone who is
still using the EMPEGCAR.SYS driver should consider switching to the
RIOHD.SYS driver.

Driver installation varies among various versions of Windows so these
instructions are deliberately a little vague...

In order to install the driver on a machine which already has the old
driver you will need to run Device Manager (accessible by right clicking
on My Computer and selecting Properties). You should select the properties
for the "Rio Car" or "empeg-car" device and choose to Update Driver.
Choose to install the driver from a specific location and point it at
wherever you've unzipped the emplode installer.

To install the driver on a machine that has not seen the device before you
should choose to specify the location and point it at wherever you've
unzipped the emplode installer.

Once the driver is installed you should be able to check the driver details.
On Windows XP it should show that you are using RIOXDRV.SYS and on older
operating systems it should show that you are using RIOHD.SYS.

Although the RIOXDRV.SYS driver has been through WHQL testing it has not yet
been signed by Microsoft. On Windows XP you will be presented with a scary
dialog box that warns you that the driver is unsigned; you should choose to
continue installation.

Now proceed with installation of the firmware.

Click on "Driver Details" or Properties to get the actual name of the driver file..

Have you done a reboot?

Have you tried removing the USB cable and plugging it back in while emplode is looking for the player?

You're giving us very little information here while at the same time being very impatient.
