Reaper Crash

Hi. I have been using Reaper for a long time and now it crashes every time, it won`t hold long enough to even play a hole song, I'm on version 375_i386, the latest for me at the moment, I am using Mac Tiger 10.4.11 and M-Box2. Hardware Overview: Model Name: iMac Model Identifier: iMac5,1 Processor Name: Intel Core 2 Duo Processor Speed: 2 GHz Number Of Processors: 1 Total Number Of Cores: 2 L2 Cache (per processor): 4 MB Memory: 2.5 GB Bus Speed: 667 MHz Boot ROM Version: IM51.0090.B09 SMC Version: 1.8f2 I have uninstalled, erased everything and installed again and all I get is this: The application REAPER quit unexpectedly. 2011-03-07 18:36:07 -0600 EXC_BAD_ACCESS (0x0001) KERN_INVALID_ADDRESS (0x0001) at 0x101bf3c0 Thread 7 Crashed: 0 _class_lookupMethodAndLoadCache + 284 1 objc_msgSend + 86 2 SWELL_QuitAutoRelease(void*) + 30 3 _ZN23audioStreamer_CoreAudio9onsamplesEPK15AudioBu fferListPS0_. + 609 4 caIOproc(unsigned long, AudioTimeStamp const*, AudioBufferList const*, AudioTimeStamp const*, AudioBufferList*, AudioTimeStamp const*, void*) + 32 5 AudioDeviceIOProcOverride(unsigned long, AudioTimeStamp const*, AudioBufferList const*, AudioTimeStamp const*, AudioBufferList*, AudioTimeStamp const*, void*) + 88 6 HP_IOProc::Call(AudioTimeStamp const&, AudioTimeStamp const&, AudioBufferList const*, AudioTimeStamp const&, AudioBufferList*) + 240 7 IOA_Device::CallIOProcs(AudioTimeStamp const&, AudioTimeStamp const&, AudioTimeStamp const&) + 274 8 HP_IOThread::PerformIO(AudioTimeStamp const&) + 1299 9 HP_IOThread::WorkLoop() + 953 ProTools and Digital Performer are working fine so i think is not a plugin issue. Please help! Thanks in advance. R.

Hi! Ever tried to roll back to 3.74 or older? Cheers! b

Thank you for your suggestion, I did that and nothing changed, so I reinstalled v.3.75 and nothing, then after shwa pointed out a standing alone plugin I checked Kontakt and there was something weird with the way it was handling samples, so I uninstalled Reaper and Kontakt (the program, not the libraries) reinstalled both and it's working!, that was the cause of the crashes, it was weird but Digital Performer and ProTools just reported some samples not working, but none of them crashed, only Reaper, I guess is more sensitive to those issues, anyway, Reaper is working like a charm now! Thanks to all, schwa, you are good. R.
