FPGA Configuration: Configuration memory is not full (Express Mode 4000XLA/XV/SpartanXL)

Problem Title:
FPGA Configuration: Configuration memory is not full (Express Mode 4000XLA/XV/SpartanXL)
Problem Description:
Urgency: Standard
General Description:
During configuration, if the DOUT pin never goes high, this might indicate
that the configuration memory is not full.
Solution 1:
In order for the FPGA to enter the Startup Sequence and complete the
configuration process all Data Frames must be correctly loaded into
memory resulting in the memory being full. DOUTgoes High to indicate
when this has occurred.
A possibility may be that the configuration process was not allowed to
complete or was terminated too early, or perhaps no configuration data
was even sent. Check the number of configuration data bytes that have
been loaded.
