Another sad story: it happened to me, when I tried to locate my re-installed Poser 4 EXE file from within Vue4 that I rather selected the Poser 5 executable. Since then, Vue4 denies ANY access to any Poser obj file import claiming that the serial number IS incorrect. I wonder how to correct this error. I've tried to rename any non-vital Vue program file but could not find out which one is in charge for inhibiting further Poser access after an erroneous selection. I'm afraid that I am (again) forced to re-install all my Vue configuration from the scratch, including the tedious process of naming dozens of serial numbers for any additionally purchased vegetation file. Not quite customer friendly, but well, it was me who did the wrong selection in first place. Any assistance would be very much welcome. Thanks in advance!
