I just tried importing a Parallels 10 VM (with no snapshots) to VMWare 7.0.1 and it still failed with the corrupt VMX file message.
I've tried downgrading Parallels 10 to 9, but it didn't work at all. Hopefully they fix this soon!
NOTE: This is still occurring in VMWare 7.1 on Dec 10, 2014. I cannot use VMware if it cannot import my Parallels VM.
