Invalid Pointer Error

Admittedly I am new to FeFlow so apologies but can someone please help me with the error message 'invalid pointer' I keep getting when trying to convert my well location shape files to observation points?
Thanks.

Could you please update to the latest FEFLOW 6.2 [i]Patch 9[/i] and try to reproduce the error message? In the main menu, please click on [b]Help[/b] and then on [b]About[/b]. Finally, click on the button [b]Check for Updates[/b].

Awesome. It worked.
Thanks
