Runtime error message!!!! Very Frustrating

Yesterday and today I'm getting a runtime error 9. I open the program, its downloads all the sweeps, It starts to entering them thm maybe 35/40 fown the list I get this a runtine error 9 message. I close the box and it closes sweepstakes ninja completely. I open it up again, the sweeps load and it doesn't show that i enter the first 35/40. I don't want to DQ myself by entering them twice. Please help me fix this bug.
