Hi, rgoins001.
If you were using LearningOnDemand, I believe the lab environment is available for six (6) months.
If you were using any other lab environment, you should contact the training provider about access to the lab. You paid for it and took the class. They should still be helpful to you, especially if they want you to buy future classes from them!
Good luck!
Best wishes, Davin Mickelson
