Need help with new clutch

Need help fast. I just replaced my clutch with a new clutch kit. When I went to
go for a test ride my peddle felt a little soft but clutch engaged fine backed
out of the driveway and put it in first it started to grab then I heard a noise like
something let go and bam nothing clutch won't grab at all. I tried bleeding the
slave but still nothing. I suspect that the shifting fork may have come free
from the throw out bearing but not sure if this would cause this problem. Also
something I found strange is that the car acts like it's driving even in neutral if
I press the gas the speedometer reads and numbers go up but I'm not
moving. Never had this happen before and it has me stumped any help would
greatly appreciated thx in advance
