nds-tti upgrade revolution pokemon white (2) problem

hey, so basically my problem is, that i get a constant errorcode =-5. no matter what i do it seems almost static lol. the website is nds-tti, i use the kernel v1.18 ttmenu.dat and the ttmenu folder provided in the general thread. i got this to work before, but i dont know how. all i know is, that i accessed a own ys menu BEFORE i loaded the games :( any help would be appreciated, maybe im making just a nooby mistake

Can you remember anythink you may have done that may have got it to work ?

no, just pokemon black seems to give an error
EDIT: i just retried it with pokemon white (1) and it didnt work either (errcode 5)... so im guessing i do something essentially wrong. it would be great if someone could give me a step by step guide. its probably plainsimple
