IMPORTANT!!! BUG FIX FOR UA v3030
Update:
You should start compression with another version of UltraArc (2400, for example) and THEN start a v.3030. Strange thing but it helps, I hope there is gonna be a fix for this soon (since we have located the problem)
Have nice day! Cheers! ;-)
Update 2:
Unfortunately, the compression fill start all over again after the end of compression. O_O
Update 3: System: Windows 7 Ultimate x64
