Catchable fatal error: Object of class stdClass.............

Hello,
Unfortunately, i have never noticed that my subscription is valid only for 3 months and i hadnt kept a backup of the newest version i was able to download, until last day of the expiration of my subscription.
ALso i have no back up of all modules and plugins I had firstly purchased/downloaded.

To be honest,i was a little annoyed when i found out that i was one of the first people to buy the component, one of the fisrt to right reviews about it, while the component was still lucking of features and being a little buggy.
Now, with same or even cheaper subscription, people have access to a much more better, full of features and addons version.

I think it is a little unfair for all first people that have bought and supported any component.

Anyway, i found the old version i had backed up and tried to install it in a joomla i have.
When trying to see the polls, i get blank page with below error:
Catchable fatal error: Object of class stdClass could not be converted to string in /home/***username***/public_html/libraries/joomla/html/parameter.php on line 119

Version i use is 1.0.8

Can i have a solution about that? Also, is there a possibilty that i gain temporary access on component, modules and pluggins, at least for the versions i have the right to download, until the date of expiration of my subscription?

Regards,
