Alright, to go over what's going on...Trying to help a friend of mine with an issue with her RCA m4002a Opal MP3 player. It says it requires 4mb of space for profiling, then immediately shuts down. At the moment, it HAS worked before, as she's connected it to her computer before hand, and was perfectly fine. Now it gives the above error. A few notes. She is running Windows 7 Starter on a mini-laptop, and has a desktop that is running Windows XP, I presume Home Edition. First thing I looked up was a way to possibly fix it. Went onto Google, and was redirected to reinstall the firmware on the RCA unit from here : http://support.rcaaudiovideo.com/downloads.aspx?product=192 Did as instructed, this all being on her laptop. Installation went smoothly, in terms of the software installing onto the computer. Once it loaded to start searching for the device "Operating system is not supported" popped up. "Wonderful." So with that in mind, I asked her to do the same on her desktop, since it was running XP, so we thought it might just need an older operating system. Which, it did. It starts to search for the device once it was plugged in, but kept resetting the search after 50%. I thought it was a bad driver, so I went to Computer > Properties > Hardware > Device Manager, and there was an error with the installation of the driver. To what I am aware, there is no CD that came with it, and it runs off what Windows has available for drivers. Plug & Play. The cable itself seems to be in almost pristine condition as well, we've tried different USB slots on the desktop, showing the exact same result.
