LabVIEW FPGA: An internal software error in the LabVIEW FPGA Module has occurred

Question

Hi,
I am trying to build a LabView FPGA VI. During compilation, I always get error stating "LabVIEW FPGA:  An internal software error in the LabVIEW FPGA Module has occurred.  Please contact National Instruments technical support at ni.com/support".  At the time, comiplation process is almost at the end.  "Final Timing (place and route)" shows as completed. When Checked the Xilinx log session, at the end it states that "  Process "Generate Programming File" completed successfully". However, I do not see any generated bitfile.
When clicked on error details, it shows following: 
LabVIEW: An unknown error occurred.
Error -2629 occurred at Error occurred while loading XML string. Invoke Node in niFpgaXml_PrettyPrint.vi->niFpgaWriteBitfileXml_Core.vi->niFpgaCompileWorker_CreateBitfile.vi->niFpgaCompileWorker_JobComplete.vi->niFpgaCompile_Worker.vi:6460001
Possible reason(s):
LabVIEW: An unknown error occurred.
I tried multiple times but so far no luck to generate bitfile for this VI.  What could be wrong here?
I am using Labview 2013

Hi Mark,
Here is the device utilization Summary. My development system is running with Windows-7 (32 bit) with 3GB RAM and Labview 2013. 
Device Utilization
Total Slices: 90.0% (11970 out of 13300)
Slice Registers: 40.7% (43258 out of 106400)
Slice LUTs: 71.6% (38103 out of 53200)
DSP48s: 1.4% (3 out of 220)
Block RAMs: 22.1% (31 out of 140)
Timing
40 MHz Onboard Clock
: 40.00 MHz (57.90 MHz maximum)
80MHz (Used by non-diagram components)
: 80.00 MHz (100.19 MHz maximum)
