Can't mount SOME iso

[solidmaple]

Some of the ISO images I ripped from DVDFab BluRay Clone will not mount. Most of them do, but with some, I get this error:
DVDFab Virtual Drive Tray -x86 has stopped working. I can check online for a solution or Close the program. I have tried ripping the problem ISO again from the DVD but it still gives the same error. Other ISOs continue to work properly.
I'm running Windows 7 Ultimate 32bit.
Any ideas would be appreciated.
Thanks

@solidmaple
might fix this bug: crash when mounting some disc from shell extension.

That did fix it, thank you. All the ISOs that did not work before now mount just fine.
