My VCF will not product any charts, I create the chart and ask it to appear on screen or to file and all that happens is a flash on the screen and nothing is saved or displayed. I have tried opening an old .vc2 file and that will not open at all either. it is almost as though the program is no longer there. I have checked and the vcf.exe is in the TMG directory. Can anyone please help me work out what is happening? I have also check the "Preferences / Advanced / config files path" and this is set correctly. The file the config is set for descendent charts - ‘vcfwdec.vcc’ is in the directory. I have also tried to reset defaults and this has not worked either.
