Can't export - No such interface supported

Can you describe exactly how your exporting. For example are you highlighting all the tracks and then the timeline. Then are you selecting Wave file 16bit, 44.1kHz??

What export properties are you selecting? After you list what your doing, it will be allot easier to help you

I've tried all formats and settings with the same results. WAV, Lame mp3 encoder, WMA
Various sample rates and bit depths, including 44.1kHz 16bit.
All Dithering settings. All properties boxes ticked and unticked. Highlighting or not highlighting the project first.

I'm using a Presonus Firestudio. All it's drivers are enabled. Never had any issues before.

I don't believe it is interface related, as running Sonar with my interface disconnected, using MME and just the laptop itself, gives the same results. (MME is what I use to listen to mixes on the laptop when away - I chose this out of Wasapi and WDM drivers as it seemed to give the best results of the three). I use ASIO with the Presonus.

I guess the best way to put this issue in one sentence would be...
'Under any circumstance, with any settings, pressing export results in error message 'No such interface suported'.

I was not disconnecting the interface to export. I always work with my interface on and export without touching it, no issues.
I was just illustrating to Chappel that I doubt the problem is audio interface related, as running Sonar on just my laptop will not let me export either.
I always work with ASIO - the MME is really just if I am travelling with my laptop and wish to listen to a project etc. MME seemed to be the one that had my laptop speakers etc. available as drivers and had no playback issues. I always got some stuttering with WDM.


Anyway...
I've solved the issue
It was something completely stupid. I was in a rush to export this to send a low quality demo to somebody, and didn't think about where I was saving the file. After clicking export and seeing the error, I immediately went into panic mode and save location became irrelevant. Turns out I've been trying to save into 'Libraries' - on Windows 7 where you can select documents/pictures etc. It doesn't seem to like it. Saving anywhere else exports with no issues :)

Thanks and sorry for wasting your time!:)
