Hello!

I have a problem with dakota soundcard during loading Nuendo.
Loading crashes on SSE Optimized Audio DSP stage (loading stage in nuendo).

Here is nuedno log:

The same thing with Dak_A16.dll.

If this error appear, second loading nuendo will be ok.

I have a x64 win xp sp2, but nuendo is 32 bit, and its using 32 bit version driver, isn't it?

I don't understand why x64 bit driver is in C:\WINDOWS\system32 folder, while 32 bit driver in C:\WINDOWS\SysWOW64. Is it normal ?

Please help!
