Java Exception in Windows - Cannot use REW to measure

[jevansoh1]

Hello,

I'm getting the following Java exception after downloading the latest version of REW and don't know how to overcome it. I'm currently unable to use the software.

Any assistance would be greatly appreciated.

Go to C:\Program Files\REW and look for a file called glazedlists-1.11.0.jar. If you find it, delete it and REW should then run OK. If you don't find that file try uninstalling then reinstalling REW.

Thanks, John. That did it.

Hi John, now I have a new problem. When I export my measurements after EQ'ing (I have a StormAudio MKII Processor and this used to work in prior versions of REW and I've tried all 3 export options/file types) when I go to import them it says invalid file "REW Identifier Not Found."

Can you help?

 

[jevansoh1]

If I try saving as text, when I go to import it says please select valid REW .txt file.

Here's the contents of the text file:

StormAudio used to use biquad values from the file generated using Send filter settings to equaliser. For issues with the REW text formats you'd have to ask StormAudio, after checking you have their latest firmware.
