You need to send a PM to Lord of The Rings to change your user name. It looks fine to me, but I realize that in your language it might mean something unprintable lol
Or you can resubscribe, although that is oficially not allowed
I imagine you are wanting to transfer your incomplete downloads, and this cannot be done. All the files you downloaded complete from Kaaza should, I imagine, be separate on your computer from Kaaza (but I know nothing about Kaaza) and you can share them in Limewire by adding them in Limewires tools > options > sharing and using "add" to add the folder(s) they are in
I hope this helps
