Yamb says file doesn't exist

[a19i23]

When muxing yamb says file doesn't exist.
I am getting this in the dialogue

[00:28:56] : YAMB 1.6.0 started !
[00:28:56] : OS type detection...
[00:28:56] : Windows XP Home Edition (version 5.1, Build 2600 : Service Pack 2)
[00:28:56] : Checking MP4Box location...MP4Box found.
[00:28:56] : Checking MediaInfo.dll...0.7.1.2 found.
[00:30:28] : Muxing started...
[00:30:28] : Muxing finished completely.

Can anyone please help.
I've checked online for help and I've tried changing the filename and also tried downgrading to an older yamb release and still nothing

Thank You:thanks:

1.6 release is outdated and not maintained anymore...please upgrade.
