VMware Fusion 5.0.5 and OS X Mavericks - Pipedream?

Hi All,

I just updated Fusion to 5.0.5 (from 5.0.4) with the hope that I could get my VMs working in OS X Yosemite.

When I try to resume a VM I get the following errors in this order:

1.  Could not open /dev/vmmon: No such file or directory.

     Please make sure that the kernel module 'vmmon' is loaded.

2.  Failed to initialize monitor device.

3.  Cannot find a valid peer process to connect to

Am I fool for thinking I can troubleshoot this, or can I avoid the Fusion 7 purchase (no upgrade available as the initial purchase was Fusion 3)?

Thanks in advance for your advice!
