windows installer does not accept login data

[lhg733]

I bought the IXEG 737 Classic Plus yesterday, and when i open the installer and try to put in my login data (which btw works perfectly fine on the X-Aviation website) it says "The provided username and password does not match or you have not purchased this product!". Under My Orders on the Website i can clearly see the IXEG though. Has anybody had a similar problem? Any help would be appreciated!
