Hi j
to tell you the truth I have never/ever used Vsigfile on MIDI. I find serial just much simpler and more reliable. You may add a COM port to your PC in 2 ways, if it doesn't have one:
-many modern PCs don't have a COM port in the rear panel but they may well have a COM socket on the motherboard where a COM can be connected. There are PCI panels (1 space) with one ore more COM ports. Just connect the wire to the motherboard if it has a socket for it, fix with a screw the PCI panel and enable the COM port in the BIOS.
-use a simple USB to COM(Serial) adapter, installing a simple driver.
Regarding why your Vsig doesn't work anymore…. it must be a configuration problem, probably in your MIDI unit. Hard to figure this out from remote though….
all the best
