Crash on changing sample rate since update

Hi, all- I'm using REAPER x64, version 4.32 on Windows 7 Professional. Since the update, when I go to Project Settings and try to change the sample rate from 44.1KHz to 48 KHz, REAPER crashes every time. Here's the error report: Problem signature: Problem Event Name: APPCRASH Application Name: reaper.exe Application Version: 4.3.2.0 Application Timestamp: 50f5f551 Fault Module Name: usbpre2_x64.dll Fault Module Version: 1.0.0.0 Fault Module Timestamp: 4d39cce9 Exception Code: c0000005 Exception Offset: 0000000000009b63 OS Version: 6.1.7601.2.1.0.256.48 Locale ID: 1033 Additional Information 1: 5850 Additional Information 2: 5850364b346d7df8d172f5a8ef51ce81 Additional Information 3: 1d6a Additional Information 4: 1d6a81d6c47fa444357c6488c95ff42d It appears to involve the driver for my audio interface, the Sound Devices USBPre 2, but since REAPER is the program that crashed (and there haven't been any recent changes to the audio interface's driver), it seemed sensible to begin by posting it here. I have been able to change to 48 KHz if I first change the sample rate in REAPER's Audio Device Settings page (the "Request Sample Rate" field), but I have to try that multiple times and endure multiple crashes each time before it will work. Also, I wanted to say that REAPER has been extremely stable for me for many months until this issue. Thanks for any light you can shed on this! -Mark

REAPER is only the host process, the crashing module is what could be the control app for your interface. - Does rolling back to the previous REAPER version you had installed fix that? - What else did you change before that started happening (any kind of update for any app, Windows update etc.)?

Thanks for the suggestions. I haven't installed anything new since the update, though I updated a few plugins yesterday. I applied these updates after this problem started, though, so they are not the cause. Next week when I have the time, I will try rolling back to 4.31, and see if it helps. Thanks! -Mark
