Explant export problems

I've been trying to export data from PDMS using the built in functionality in ExPLANT-I

My configuration is the following

ATTRIBUTE_FILE xml
DGN_FILE yes
ATTRIBUTE_LINKAGE 32768 0
FILE_HEADER ||
ELEMENT_HEADER ||
ATTRIBUTE_FORMAT ||
OUTPUT_UNITS MM DECIMAL 1
OUTPUT_UNITS DISTANCE MM
OUTPUT_UNITS BORE NOMINAL MM DECIMAL 1
GRAPHIC_GROUPS ON
----------------------------------------------------------------------------

Then i have several types of data i include. I will mention this works perfectly for exporting smaller data sets.
When a bigger data export start something wierd happends, here is a few sections copied from the same XML file produced.

In Design Utilities --> Export -->Select Driver --> Explant I (Intergraph)

After this Utilities -->Export -->Create It will open a Form

Mention file name as some xxx.dgn

and Include which Sites you need for export.

It will give Correct Output.

Hi and thank you for your reply.
Seems i have no option to select Explant I (Intergraph). the only thing i can select from this is review.

however for exporting i have just made a program that is integrated to pdms, using command line operations like:

           Run(Command.CreateCommand("export system /explant"));
           Run(Command.CreateCommand("export autocolour on"));
           Run(Command.CreateCommand("export option \'configuration\' \'" + pathToMyConfig.cfg + "\'"));
           Run(Command.CreateCommand("export file /" + target + " overwrite"));
           Run(Command.CreateCommand("export holes on"));
Run(Command.CreateCommand("export ce")); < Loop here on all elements to export >
Run(Command.CreateCommand("export option 'Seedfile' '" + mySeed.dgn + "'"));
           Run(Command.CreateCommand("export finish"));

Seems to be working ok to me initially its just when i come across very large datasets that for some reson the ID gets messed up.
