Error importing Act! 2007/08 data

[frstred]

I am using the trial version of Outlook 2007 with BCM. It imports the data
from my Act! database for about 20 minutes and then quits, leaving the
following error in the log:
Type,Message,RowKey
Contact, System.OutOfMemoryException: Exception of type
'System.OutOfMemoryException' was thrown.
How can this be fixed. I have no need for the 2007 product unless I can
convert from Act! Thanks.
