The full version number of MC: 28.0.106 (64 bit)
A description of the issue: JRiver MC Crashes when trying to convert several different .MP3 files (with various bitrates, from 32 to 128 kbps, of various lengths and sizes) to .MP3 files (we're trying to encode with 64 kbps, but we've discovered the issue occurs with any bitrate) using CBR/ABR Encoding. We found the issue difficult to reproduce with small files, but the issue is consistent with a file 60MB in size and an hour long
Step-by-step instructions on how you reproduce the issue (whenever possible): Opening JRiver, browsing to a file, right clicking on the file, selecting "Convert Format" in the drop down menu, (modifying options isn't nessecary to cause the crash, but our options are 64 kpbs, CBR Enabled) and clicking the big button labeled "Convert". J River crashed directly to windows without a black screen or error message.
The steps you've taken to investigate or address the issue (see above). We've tried different sizes and formats, we tried on different hardware.
Any patterns you've noticed during testing (see above): We've found that the problem is difficult (but not impossible) to reproduce with smaller files, but is consistent and reproducible with large files (Over 1 hour in length and over 50 MB in size
