need help with R4 for DS... please?!

if anybody has experiance setting up an R4 for DSlite... please.. help?...
ive formatted the 2gb micro SD to FAT32 and added the four items that are needed.. but when i plug it into the R4 card and turn it on... it just sits on the "loading..." screen...
as if that wasnt a big enough headache.. occassionally itll work but then come up with an error on the touchscreen saying something along the lines of the moonshl folder was deleted or moved... then all itll do is play music or videos... nothing else..
seriously.. ive been trying to get this working for so long now its stopped making sense!! :s
if anyone can help itd be greatly appreciated!!
