Having problems with Valves Pro

Hello,

I created some tracks in Reason using Valves pro in the Kontak 7vst player, specifically using three independent tracks all using the "Valves Pro - solo ribbon" file. Everything sounded great and worked. I opened them up after about 6 months and now these same files - untoucehd in all that time - are all different. What used to be nice legato line are all very staccato. When I play the sound on the keyboard it is doing some sort of grace note thing…like it won't play a single key at all, but if I hold one key and then press another it will play a short grace note from the first to the second.

It should be noted that this is across multiple separate Reason files, same problem in all of them.

I feel like there is some simple thing I am overlooking. But what's very strange is that I have done nothing to these files since creating them.

Can anyone help?
