Need to download again?

[Professor_G]

I have been playing DDO with no problem since downloading it on 11/11/09.

Tonight I tried to start the game up using the launcher, a download option is all I get.

My concerns are:

WHY do I seemingly need to download the game again?

IF I do download the game, will I be able to play my character, or will I have to start all over again?

My folder with DDO in it is still in my PC. I do not think it is corrupted in any way.

PLEASE HELP!
