Sync project issues

when I try to sync my project this message pops up:

unable to delete F:/EFFECTS/config.csv

it asks" retry" [which does not work] or “abort”

any help appreciated, I am at a loss

Try quitting and launching the BBM. Then try to sync again. If that doesn’t work, try to Export Project to the SD card; overwrite the contents and then accept the prompt for future sync.
