RCA EMUSIC1 (FM6652) firmware found...
If none of the above solutions work, you can probably bring your EMUSIC1 back to life by reflashing its firmware. It's based on a SigmaTel chip, which is actually not a bad system, and their updater is very robust. Unfortunately, the firmware for my EMUSIC1 wasn't on the included CD, so when it died, I couldn't reflash it. RCA's western support sites also don't have the firmware available, and their email support is just an autoanswer stub. This product is packaged as a free giveaway when you buy 180 song downloads from emusic, so I guess RCA considers it a throwaway item.
But I didn't want to throw it away, and after much Googling, I finally used the Google translation feature to find a Chinese version of the firmware! Seems RCA takes better care of their customers in The Middle Kingdom...
In China the product is known as FM6652. This firmware is for the Chinese market I guess: It will first bootup in Chinese, but you can go through the menu and change the language to English, and from then on it will always boot in English. Note that ONLY English as well as the two variants of Chinese are available with this firmware. In the ReadMe file it shows version 1.716.2.001 If you use the device menu to show version, it shows version 1.01
Anyways, it brought my player back to life. I've been using it for about a week and it seems to work exactly like the firmware it originally had on it. BUT so far it hasn't exhibited any of the flakiness of the original (no more freezing of Windows during file transfers, etc! So far, at least...). I'm not making any guarantees that this is a better firmware version than the US market original, but it seems to be. The only bad news is, it hasn't improved the very short battery life - I get like two or three hours, same as before... OK, I do like my music LOUD!

To resurrect a dead EMUSIC1 on a Windows XP machine, download and decompress the rar file, then dive down through the folders, clicking on 6652... at each level until you come to stupdaterapp.exe Double click that and it will start looking for your EMUSIC1. Hold the PLAY button in on the EMUSIC1 while plugging it into the USB port. Keep that button down until you see that the program has started to find your player, then follow the prompts in the program. Note that the program will reformat the flash memory and erase any songs you have on it.
