PT Qestion

[golfcchs]

When I am importing hands from empire to PT in get in error message:
Import Finished With Errors - The import finished but there were errors. The error messages were written to a file named c:\program files\poker tracker v2\PTAI_ErrorFile_20050831_205420.txt - 41 file(s) read - 29 new hand(s) were imported.
What does this mean and how can I fix it?
Thanks allot for the help.
