Captivate 8 Subscription

Hi all.

I am currently developing a set of ERP training products. Captivate is the standard corporate tool for this purpose and I have been working on a trial licence / download while the Procurement people buy a full licence.  However, I am now stuck in a loop concerning versions.  My laptop configuration requires me to run Cp 8.  Procurement have secured a full licence for Cp 9, which does not port retrospectively to Cp 8.  For me to use Cp 9 would require IT to perform a full laptop rebuild, with all the associated downtime and delay to completing my products.

Is there any way we can either buy a licence for Cp 8 or else subscribe to Cp 8 for 1-2 months and then upgrade my laptop and Cp version later when project timelines are not so tight ?

Many thanks for any advice !
