to RU filesonic links you need filesonic premium ! you can't RU any link without premium acc .
well i did it from RS to Filesonic and RS to fileserve same day one by one, My RS account got suspended and got an email that account was h-a-c-k-ed with list of IP network and they sent a link to reset the account password. So if you still want to use it RS to FSN then that whole day use it for RS to filesonic and next day try RS to FS.Also a question can it be done vice-e-versa..???
