Hi,
Chimera is saying that your phi file output from Delphi contains inconsistent information, like maybe it got truncated.  I do not know if it is possible to fix the phi file, sorry. 

The DelPhi files that Chimera can read are from the academic version of DelPhi, as mentioned here:
<http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/filetypes.html#esp>

If you have some other version of DelPhi associated with a commercial package, maybe the format is different and Chimera does not know how to read it.

Linked to the last section of this tutorial, there is an example DelPhi phi file (3eebB.phi) that Chimera can read:
<http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/tutorials/surfprop.html>

I hope this helps,
Elaine
