Can’t install wazapp in any way

[Tiff-tiff]

Hi!
I use wazapp for a Nokia N9.
I already had the app on my mobile but I had some issues, like I couldn’t sync the contacts or send pictures, so I decided to remove it and install it again but when I tried to do it I got the message “fail reason: old version” and never got the verification code so I can’t get the wazapp to work. I got the code from CODeRUS but it was a 6 digits code with a – in between and wazapp requires a 3 digit code. I tried everything I found on this web and other websites (even installing an old version of wazapp 0.9.13, 0.9.17, 0.9.20…) and everytime I got a different fail reason.
I really need to solve this.
Please help me! Thanks!
