screen turns blue when i download a song
 

okay well i'm having some weird problems everytime i load up limewire.
i'm currently using limewire 4. 14. 10
well, anyway
it's fine whilst i'm searching in the song i'm wanting to download,
once i click on the song to download it, after about 10seconds the screen will go blue and it comes up something like "press any button to continue, to restart press ctrl+alt+delete" something like that anyway, so when i press a button to continue, if i hover over the limewire icon in the corner it'll disappear, meaning i'll have to load it up again.
this happened every-single-time i loaded it up, so in the end i un-installed it and gave up :/ (mhm, i removed it a few weeks/month ago.)
anyway, i've just gotten it back to see if it'll work yet,
i loaded it up last night and it was fine, so i thought the problem/error had gone away :/
loaded it up before and i have the same problem all over again.
a while ago when i had limewire, i never had this problem.

i use limewire on windows millennium and on a mac, and i have the same problem on both.

mhmm, what does this mean? :/

thanks.
