I've had somewhat of an epic battle recently getting LD2K working under Windows 7 64bit recently, but it would seem that my biggest issues was a hardware one. PCI bus not playing well. Anywho, It works now and I tried a ton of things in the meantime and might be able to help you out here Pelosh.
From the top, after you install the software, does the software fail out with an error code, what is that code?(In my case it was -1003). Is the card visible in DevMan *even* if it is showing up as the default "PCI Digital Signal Acquisition Controller" ?
In C:\Windows\LD2000.ini - Does it start out as listed below:

On line 14, CommWindowAtStartup=0, I switched this to 1 and it helped out immensely to see if the system was even attempting to talk to the card or not.When running the program If you don't see anything other than "InitialQMCheck" in the window, that says a lot and leads toward a hardware configuration issue.
I ended up finding my solution in the computers BIOS by resetting ESCD Data and changing the IRQ mapping to manual.
Unless the card is fried, I'm sure we can figure it out.
