I've tried uploading mesh in V3. Each time I clicked on Model under build I was crashed out, why?

Just to eliminate one possible cause, have you recently installed Microsoft Skydrive?  That causes an immediate crash whenever you do anything that involves the viewer opening a file browser.   The bug is described at VWR-28843 (and Latif Khalifa describes a fix -- other than uninstalling Skydrive, of course -- here).

Haven't tried uploading on the main grid today but Aditi uploads have been not working and often giving a "we may have charged you but it didn't process" type error message since last night. Might be related. Typically there have been no uploading issues on Aditi.  Tried both LL and FS viewer. Only LL viewer actually "tried" to upload .

As addition to Innula's answer: There are lot's of system tools that can cause the viewer to crash when opening file dialogs, like Microsoft Skydrive, Google Drive, Apple iCloud etc. There have even been reports the Nokia PC suite can cause that. So check not only for Skydrive but also for other kind of applications that somehow integrate into the Windows Explorer.
