Online Armor crash

The strangest thing happened today - Online Armor 4.0.0.15 (the paid version) suddenly stopped working when my laptop came out of hibernation. The error report looks like this:

Problem signature:
Problem Event Name: APPCRASH
Application Name: oasrv.exe
Application Version: 4.0.0.15
Application Timestamp: 2a425e19
Fault Module Name: ntdll.dll

Exception Code: c0000005

I did find an identical problem on the Online Armor boards but no solution:

A similar thing seems to have happened in this thread. Several reports but again, no solution:

Are there any more reports of this error? Is it perhaps version-specific?

 

I had the same crash report with Online Armor Premium. I noticed the "crash" message on my desktop after I had been away for a while. But then I checked services and noticed the oasrv.exe was running. So maybe upon crash the service re-starts? I also noticed no crash reports since the last OA update.

 

Update: A downgrade to the last stable 3.5 build solved the problem:
