Nope. You shall see the number of credits in the workshop. You can now use all the options. Make sure that you tick the box "use credits" in the render tab. This is to ensure that you can still make free renders if required even if you have credits available. If you don't use credits and you want to use options that require credits, options will turn red and you won't be able to start the render. To summarise, with or without credits all the options are available to be set up in the workshop however if you selected options that requires credits it won't let you start the render and you will see an error message.

Let me know if I am not clear enough.

Thank you for your reply but these all things have been done by me. At "workshop" in "3D rendering", the space for credits is $000. I also tick the box for using "credits". The options turn red as you said which indicates that I am still using the free version. I also have got E-mail that your payment is received by Mecabricks.

Do you (already) see the amount of bought credits in your workshop?

@omparam It is fixed. You shall be all googd to go now. I will investigate why it has not been transferred directly against your user account. That is the first time it happened in 2 years that I use Paypal.

Thank you now its working properly. I also have done some renders on it. It works fine.

No worries. Sorry the delay.
