Error message trying to connect to Netsuite

I'm attempting to create a connection with Netsuite and I get this error message.

ERROR: duplicate key value violates unique constraint "ServiceTableDefinitions_pk"
  Detail: Key ("SessionId", "SessionResourceId", "ServiceTableDefinitionId", "LCName")=(t20434735s121413_38826vFk1JV2DG6CAVTXW25SDDXSBW4NM, 1JV2V7HFGFHT8V7ZP11D3V5SK, , country) already exists.

I don't know what it means.

Any help would be appreciated.
