hello guys,
I had this issue when i was trying to upload my documents. So may be I can try to help. As it indicates "Make sure that the information entered in your Arrima profile - your names, first names, gender, date of birth and your file number - is identical to that transmitted in your online request for temporary selection for studies or that received by the post". This appeared to me as well. And when I tried to find out what went wrong it took one full day to get in there. So in my case the mistake was not in my name, gender, date of birth or file number. Rather there was an error in the address which I had put. So make sure that the address you have entered in your CAQ application is the same what you enter here. Because in CAQ they ask you to enter the address where you want your CAQ to be posted, and when you are signing on at ARRIMA portal it asks for some address and we happen to put our permanent address and this doesn't work at the end. So besides the above mentioned errors (names, gender etc...) plse cross check with your address and make sure its the same in CAQ as well as at ARRIMA. Do let em know if it worked.
All the best
