Nobody?
I guess this is due to people not knowing what to guess first. You have not given us anything to work on, except that you use MSP8.
It would certainly make it a lot easier if you were to state at least the basics. In your profile, there is a section where you can insert your system specific data. Not that it would be of much help in this particular case but it would be a start.
Now, back to your problem. How do you connect your camera? Which capture device did you select? Did you select a device control?
I don't know much about MSP8, never used it, although I have downloaded the trial. I'm also not at my video machine right now and have to try to picture the capture module, as I know it (MSP7), from memory.
On the menu bar, there should be items for Set Up and for Capture. Can you give us the details on what is selected there? Maybe a screen shot or a listing you can type here? I'm sure your problem stems from the settings there or your connection. Do you use a firewire cable?
I'm afraid, without giving any details, you could wait a long time for any response. I too ignored your post initially for that reason but in the end felt sorry for you (no offence intended).
Rest assured, this is very likely an easy one but we need to know what you did so far.
