Error On Search()

Hello everybody.

i just downloaded the FullTextSearch Engine and wrote a little test program. on the search function it returns an error i can not figure out:

Corrupt Full-Text Index for table "d:\development\dev\mm\kess\comast.dbf" (noise words do not match NoiseWordsCount attribute)
Expression evaluator failed.

when i created the index i used the sample sysntax provided ("FldString" is a string with all character and memo fields in the source table):

RetValue = oFullText.CreateIndex(;
   'oeno', ;
   FldString, ;
   .T., ;
   FILETOSTR('FullTextNoise.txt'), ;
   2)

does anyone have an idea?

thanks for all your help in advance!
