Sonar 8.5 problems with Vielklang from Zplane

Hi
I have a problem with Vielklang (from Zplane) no longer working after upgrading to 8.5.

Tim Flohrer from Zplane has requested an evaluation copy of 8.5 from Cakewalk but they have not replied to him after three weeks and I know he has contacted them a couple of times.
I wondered if anyone else used Vielklang and if yes have they got it working OK with Sonar 8.5. It would be helpful to know if this is a problem unique to my set up which is:-

Antec Sonata-III w/True Power Trio 650w PS                                         
QX9650                  
Freezer 7 Pro                                                                     
Abit P35 chipset motherboard (TI Firewire, USB 2.0)                                                  
4GB Corsair DDR2/800                                
3200GB Seagate SATA-II HD (7200RPM/16MB cache)
1TB Seagate SATA-II HD (7200RPM/32MB cache)
Radeon x1550 Pro (512MB – dual head)                                
20x Lite-on DVD/RW w/Lightscribe
Pyro PCIe TI Firewire controller
External USB US Robotics 56k modem
Acronis True Image 11                                 
Windows XP Pro
RME Fireface 800
All latest drivers etc - even downloaded the latest Directx and Radeon drivers.

Also if anyone from Cakewalk reads this, is there any chance that Zplane can have an evaluation copy so they can investigate what the problem may be?
Thanks
Nigel

PS Sorry about all the different type faces / sizes etc  - I cut and pasted my computer specs from an email and it all went a bit pear shaped so to speak! Afterwards the forum entry  would not allow me to reformat the text - strange!!

Hi Bit
Sorry about not being specific about the problem, my fault. I should have been more specific - I suppose I was just wondering if anyone else who uses Sonar also uses Veilklang and had had any issues generally - in my case it's not a product I use regularly, only occasionally for specific projects, that's why I did not notice immediately when I upgraded to 8.5 that it had ceased to work.
The problem is Vielklang used to work without problems with versions up to and including version 8 - after upgrading to 8.5.1 I noticed that whilst Vielklang loads, you can drag the audio onto the main window and it appears to process the audio - you get the processed audio in "blobs" (very similar to Melodyne) Unfortaunely there is no output.
Tried everything including uninstalling and reinstalling etc without success.
I reported the problem to Zplane and they informed me that as the problem seemed to stem from when I upgraded to 8.5 they would need to try Vielklang with Sonar 8.5 (nothing else whatsoever had been changed on my set up)   -   Tim at Zplane told me he had checked Cakewalk's website and the only version that he could see was available for evaluation and download was version 8. I have just checked and he appears correct, namley version 8.0.2 seems the only version available for web trial. If 8.5 or higher is available, can you let me have the download address so I can pass this onto Zplane - that would be very much appreciated.
Thanks

Hi Bit
Thanks for this, that's a good idea I reckon - see always good to get a different view on things!
I'll contact support and see if I can't get them talking!
Cheers
Nigel
