NOD32 won’t work as my external scanner in hMail! Help

Here is the command line I use: 
"C:Program FilesESETESET NOD32 Antivirusecls.exe" –files –no-boots –arch –mail –sfx –rtp –adware –unsafe –unwanted –pattern –heur –adv-heur –action=clean –no-quarantine –log-file=C:tmplogNOD32.log –log-all "%FILE%" 

The file is not scanned ( I get a return value of 100) and in the NOD32 log it says: 
ECLS Command-line scanner, version 3.0.621.0, (C) 2007 ESET, spol. s r.o. 
Scanner initialization failed. 

After trying various parameters (and thus making the command longer) I got the following error in the ERROR log of hmail: 

"ERROR" 2996 "2008-01-23 10:13:57.121" "Source: ADOConnection::Execute(), Code: HM10044, Description: Error while executing SQL statement:

Any ideas please? Is this due to the NOD32 or I missed something in my parameters?

Thanks.
