only one line in my utf-8 csv file migrates successfully, the others cause many instances of this error:

SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry 'node-13' for key 'PRIMARY'

ive tried:
using with or without headers.
using numbers or words as headers.
I've removed any cck fields that won't be populated in the migration.

everytime i get the error i use backup and migrate to redo the site, I clear cache again and try another variation of above. After 15 tries no go. i've run out of ideas. please help.

was never able to fix this. Since it was a new site anyway I reinstalled everything and activated only the essential modules (feeds, taxonomy manager, cck, views, feeds tamper dev, backup and migrate), and it worked fine ever since.
