I haven't been able to access those logs, nor does my MacBook Crash Reporter prove to be useful as it doesn't show the actual report to me after it has crashed. But I did saved my System Profile with all the hardware, software, network information. Only problem is what do I do with it now? I'm wondering if Linden Labs receives any news about my account's crashings. That would be useful but I doubt they'd investigate it.
Oh and imporant thing: I've logged in succesfully with an alternative account and SL seemed to work fine. So now that we can rule SL's server out, does this mean there's probably something on my main avatar or inventory that prevents SL from running? If so, what is there to do about this? I can't detach or delete the 'thing' that causes this, seeing as I'm not getting access to my main account. And even I did for a few minutes, how am I going to scan my total inventory on bugs?
