Can you please make a screenshot of what you mean with "it downloaded but came up wid a cross. it dont work tho..jst has it in my control panel"
PS1: Downloading a program is not the same as installing a program. Downloading something means copying it from the internet to your local hard drive.
Installing means starting up the program on your hard drive.
Aka, downloading something can't result in "comming up with a cross".
Are you able to install Messenger Plus! properly? Are there any errors which pop up?
Tip: Do not click on links on the internet and select "open" or "run" or "start". You better select "Save" to first save the file to your hard disk. When the file is completely downloaded you press "ok" (not "open" or "run" or whatever else). When the download dialog is closed you go to your hard disk and you double click on the program you just downloaded. This prevents many possible and common problems with caches, etc., which may lead to installation problems and corrupted files.
PS2: this is a forum, without a text length limit, it is not a text message on your mobile phone. Reading short talk is very annoying (and decyphering is slow). Try to write proper words. It would be much easier to read your posts and understand you.
