using data with around 500000 rows for text analysis

I installed rapidminer academia version to work on my academic project on bigdata. When I tried loading a file which has around 500000 rows, the tool said "your license supports upto 10000 rows of data. Please upgrade to use all your data". 

I applied for the academic version, which gave me a link immediately to install the tool. I'm not sure if i'll get another link or approval to download the academic version or the one I installed is the right one.

Please help me with this as my project submission is due in 10 days.
