Unable to open works document

I'm trying to open a file that is saved in Works 8 but I keep getting this message:

Works cannot open "C:\Documents and Settings\HP_Administrator\Desktop\Paid To wps". The file may be in use by another application, the file format may not be supported by any of the installed converters, or the file may be corrupt.

I don't know what this means, but I really need that file. Can anyone help me out?

Thanks.

 

You could try installing the windows compatibility pack from microsoft , see if that does the trick.

Is the file called "Paid To wps" or "Paid To.wps"?
If it is not the latter, it will not be recognized as a Works document.
