Buzz Me Pro Error Message! Help!

Hi, I just downloaded buzz me pro for my blackbery curve 8900 from blackberry app world but when I go to open it it says the following error message:

'BuzzmePro:Class'com.bigtincan.blackberry.buzzmepr o.storage.storeusersettings' multiply defined'

Ive contacted big tin can but in the meantime thought i should try here to see if anyone else has had the same problem?

I had already downloaded the free buzz me which works fine! I thought that maybe the pro version wasnt working cos I still have the origional?

Any help would be much appreciated!

Abbi :)
