need limewire pro 4.18

[ezrajl]

i have a mac with osx leopard 10.5.6 and i downloaded limewire pro 5 upgrade a few days ago and cant even open limewire anymore. i read the problem is not my os but that i have a power pc mac not an intel based mac. ok thats fine. but now im trying to downgrade back to lw pro 4.18 and can only get the basic version because i cannot find a link on limewire.com for version 4 for osx. i already emailed the support form and have not gotten a response for two days. is there ANYWHERE i can get this version. i still have a few months on my "membership" so what can i do to get it back?

please help
