k don't know if this helps but...
when im on ng it tells me that i'm not logged on for medals even tho i am.
what's wierd is that i just used my moms comp to go on newgrounds and play "it's a nice day today" and got the same message, but when i played i still got the "failure to communicate" medal, which i got to keep.
i just tried to get my last "spewer" medal on my comp and it did the same thing it did before, meaning that i don't have the final medal for it still T_T
