Hmm...I don't. WinZip costs money, and I only pay for things I'm going to use reasonably regularly. I almost never bother compressing things any more. ; )
WinRAR is available for download
here. The version I have is quite old, but also completely safe; I'm a bit of a paranoid when it comes to spyware and viruses. The new version should be safe too.
Alternatively, someone who has both WinRAR and WinZip might be willing to download all three of my rars, and zip them up together into one file to upload...?
In the meantime, here's the Bug1 .trn file. I just renamed it .txt; the data should remain the same. Hopefully you can change the extension back to .trn and take a look at it. If this works, and you need me to, I could upload the other two files this way as well...
