I paid 4 times for this course, still no access to it

Dear all,

I started the “Getting Started with Accelerated Computing in Modern CUDA C++”, but when after I did 25% of I started getting “We encountered an error. Please try again.” and the course wrongly shows 100% completed and I cannot resume it.
I created different profiles and paid 3 more times, hoping to have access to the course from scratch. The payments were successful, but didn’t get any new enrollment. The last day to enroll is tomorrow.
Please help.

Please help.
