Merge WMV files - avidemux fails

[pospiech]

Hello
I have a 30 min Video that was split up into 27 separate video files.

I am searching for a simple merge/concat solution.
I tried avidemux 2.7.1.

But this fails with an assertion: _offset < pakSize, line 33 file ... /ADM_asfloh.h

How can I report this error and which other solutions could I try?

My system is Windows 10, 64 bit.

Here the crash log:
ADM_setCrashHook [libADM_core6.dll]
ADM_setCrashHook [libADM_core6.dll]
