having problem downloading from megaupload.

the problem im having is slow download speed from megaupload.ive been downloading character packs for a program called mugen.the first 2 i downloaded a few days ago and they downloaded at normal speed.since then everything i download from megaupload is downloading really slow.are they cutting my speed cause im not a premium member??(every other site i use seems to download/run at normal speed).is there a way i can download stuff at good speeds without becoming a premium member???
ive scanned the files so i dont think its virus related.
ive checked my internet usage and havnt gone over my limit.
any help would be appreciated.
