iPage/SMF Nightmare! Cannot install Ad Seller Pro

[HappyHooligan]

Hi, can you help me please.
I've moved host from 1and1 to iPage and have been having a few problems with mods for some reason?
I have an old version of Ad Seller Pro which I wanted to upload and install but I'm getting "Some of the files the package manager needs to modify are not writable. This needs to be changed by logging into FTP and using it to chmod or create the files and folders. Your FTP information may be temporarily cached for proper operation of the package manager. Note you can also do this manually using an FTP client - to view a list of the affected files please click here."
Then underneath that I have "Could not contact server."
I have put in the relevant info for the following but still no luck
TP Server: 
Port: 
Username:
Password:
Local path to SMF:
I've been on the chat room with iPage staff and the last thing  they said to me was...
"Please make sure to use hosting username and password to connect to FTP servers. I suggest that you contact the Forum or application vendor if the issue persists."
Also how can I find out if I can upgrade Ad Seller Pro. I don't have the email I received as my PC died on me and I lost the lot. Is there way to check???

Thanks in advance

PM me the email used to order.
I can then send you the license information to download the latest ad seller pro.

If you need help with installing we can do that as well but that requires us to have an admin account on the forum and you need to send us ftp information.

Hi I got the license, thanks. I couldn't find where to download the new version though so downloaded it from the post a few down from mine.
I PM'd you as I'm still having trouble setting up Ad Seller Pro. I setup an admin account on my forum for you. Hope it works ok? If you need any other info just ask.

Thanks again guys
