[SOLVED] Randomly doesnt work on products

Hi Dan,
We updated either free version, either demo version.
Please try again. I hope it will work "anytime"!
If not please, send to our support e-mail the screenshot with the errors experimented. You will help us to consolidate the software.
Thank you.

Could you please open this request on the WooPrice Calculator (Pro)?
Thanks

I have the plugin and it works great until it doesn't. I created a product and created a field and calculator but for some reason after the first three successful implementations it doesn't work on any additional products. They don't even recognize that its a calculator product
