I just had this problem and fixed it. I was dissapointed seeing this thread in necro mode.
When i looked into the values that FT_nIFRet=FT_INIT(strConfigName[],FT_nIFCont) was giving back, it gave a value of "1". As per the comments in the RSI_CREATE function:
;# RSIFILENOTFOUND: File not found
So went to a restore point that was working before and updated my programs.
This fixed my issue.
