I would like you to:
1. Hit the Windows Start button
2. Type in: Device Manager, then hit enter. This will start the Windows Device Manager
3. Expand the tab for Sound, Video and Game Controllers.
4. You SHOULD see an entry for your UA-25 device - might be called Roland/Edirol UA-25 - something like that. Double-click on that entry, and it will open up the Properties dialog box for that device
5. Look to see if it tells you the device is working properly. If it is not (or you saw like a yellow triangle next to it in the list of devices - then you have a bad install of drivers. If the device IS working properly, then I would like you to click on the Drivers tab for the device, and tell me what the Driver Provider, the Driver Date, and the Driver Version.
Also, I asked you to list for me two other things. First, I would like a detailed list of specs for your computer system, so that I know (and the others in the forum that may help with this for you) what kind of system you are working with. It will help guide us in how we approach helping you. Without that info, many forum folk would not even respond to you, other than to tell you once to provide that info. The second thing I asked you to post was to let me know if you wanted to be able to call me on my cell to help walk you through this set of issues.
So, gather your thoughts and choose a path. I and we stand ready to help you, but can only do that if you respond to the rather basic requests that have been made of you for more info.
