VIX and Workstation version compatibility

I think i am having problems with the the workstation and vix not being the right versions ( compatibility wise ).

I have a virtual machine that was created using 6.0 . 

I had some working code in c++ and perl.

now , i upgraded to the latest workstation and vix available for download.

I verified  the version  of the workstation to be 6.0.1.

The vix i installed is  VMware-vix-1.1.0-45731.exe .

now , program gives errors .

i get the following error for the perl script

"VMOpen() failed, 3008 Cannot connect to the virtual machine"

also,  the VIX_API_VERSION is 2 , is this right ?

here is the first few lines of the script
