flash menus not working?

I have a Sony Ericsson C510 and I need some help with installing some flash menus when using A2 Uploader.
I have had successful and unsuccessful attempts with them (more unsuccessful though T-T) and a couple problems keep on occurring:

1) The theme works, but the flash menu doesn't. I've made sure I put it in the correct path: tpa/preset/system/desktop/flash
But it just doesn't show or work. The default menu is shown instead (the non-flash one).

2) The theme works, and the flash menu works. However, when I see the flash menu the words for the icon show up with caps with underscores, like TXT_MESSAGES. In addition, when I select the icon it is unresponsive. Again, i've made sure I put the flash file in the correct path as stated above.

If anyone has an idea on what I'm doing wrong or how to fix it, ti'd be greatly appreciated.

But I also have some other questions...how do you get skins for the media player and what are standby themes about?
One more still (sorry, alot to ask, I'm a noob here :S) when I'm trying to put different startup images and sounds am I supposed to delete the one that is already on the phone? When I just add the new one into the folder: tpa/preset/system/settings, the original one shows. It won't let me delete the original file though.


Any help would be great! Thanks for reading!
