Solidworks 2007 64bit save as .dwg

I am using Solidworks2007 SP4.0 64bit. I can not consistantlywrite .dwg files from my .slddrw. One minute it will work and thenext minute it will not. This problem started when we started usingSW2007 SP0. We have three seats of 64 bit and they all have thesame problem. We have one seat of 32 bit and it works flawlessly. Ihad 32 bit a up until a few weeks ago and I never had any problemswriting .dwg's. I have tried saving as different versions and thatdidn't work either. I can not find any info. regarding this atSolidworks.com or on any search engine.

We need this function to provide cad files to our customers. Wetypically use a macro to do this since it invovles multiple sheetdrawings. Saving does not work with the macro or by doing the file,save as method either.

Does anyone else have this problem?

Thanks in advance!SolidworksImport export
