DD0033 - Unknown NCI Code value for Code List "XXX"

Hi,

Intentionally posted in the "Troubleshooting and Problems" forum as this is only occurring for one user. When they are trying to validate the define every single code list is displaying the DD0033 P21 ID error. Yet, when I run the validator I do not get this problem.

For obvious reasons, I cannot send the Define.XML itself but attached is photo of the messages.

Also, here is the XML code.

<CodeList OID="CL.AE.ACN" Name="Action Taken with Study Treatment (AE)" DataType="text">
    <EnumeratedItem CodedValue="DRUG WITHDRAWN">
        <Alias Name="C49502" Context="nci:ExtCodeID"/>
    </EnumeratedItem>
    <EnumeratedItem CodedValue="NOT APPLICABLE">
        <Alias Name="C48660" Context="nci:ExtCodeID"/>
    </EnumeratedItem>
    <EnumeratedItem CodedValue="UNKNOWN">
        <Alias Name="C17998" Context="nci:ExtCodeID"/>
    </EnumeratedItem>
    <Alias Name="C66767" Context="nci:ExtCodeID"/>
</CodeList>

I have tried deleting the P21 folder automatically created by P21 upon launch (%systemdrive%/users/%username%/My documents) in the hope it would rebuild, but no luck,

Thanks
Craig
