Hi,
When Octane was new, I purchased the 1st generation and was using it all right till I reformatted my laptop.many yrs later, here I am, have just installed the 1.55 version(tried lower version as 2.0 doesnt work) and its showing me a blank grey screen on my interface. I have update my graphic card and checked on my preference my cuda device is 6.50.
Is there something I am missing? please advise. Appreciate it.
Still no CUDA link?

It looks like your card is too old.
Version 1.55 requires a compute 2.0 or greater enabled card. You could try Octane 1.2, it still supports the older cards.
