Hello,
when I place UV22HR into my plug-in chain in the Batch Processor and use multitasking (anything more than 1 core) then “a serious error occurs inside the plugin UV22HR”. No such error occurs for the 1-core setting and no other plugins seem to be affected by this issue.
Input Files Format: WAV 44.1kHz/24bit (about 10 files to process)
Output Files Format: WAV 44.1kHz/16bit
WaveLab 7.2.1 64bit
Windows 7 64bit
Intel Core i5 with hyperthreading on
I am aware of the fact that this issue might be difficult to replicate. Anyway, I would be glad if you can check it 
Best regards
Miloslav
