Inable to open Voltz

[servo270]

I've had the technic pack for a little over a week now, and have played with Voltz several times, but only today was it not logging on.

When I clicked "play", it would put out some text, until it got to the "processing version 0%" tag, where it would stop, then close the output window.

It did the same thing after a reboot of the computer I'm using (mid-range laptop, which ran it fine earlier).

The console outputs this when I try to log on. Anyone know how to decipher this?

java.io.FileNotFoundException: C:\Users\Patrick\AppData\Roaming\.technic\modpacks\voltz\bin\natives\OpenAL32.dll (The process cannot access the file because it is being used by another process)
