I've bought VMware Workstation 8 just today. After the installation I launched it and the application noticed me that "several modules must be compiled and loaded into the running kernel".
During the process, VMware noticed me that was impossible to configure Virtual Network Devices and at the end, was impossible to start the services.
The last message said that further information could be found at this address:
So, I've pasted the content of the log message here.
Can you help me or, rather, you suggest to wait for future updates of Ubuntu? My desktop environment is Unity.
