i Have the same problem. I cant preview any video files even the ones i have downloaded already. But i can listen and preview music just fine? i need some help here. thanks

give up
 

Don't bother trying to contact LW tech support, I got some A-Hole who kept whinning because I didn't give him an 'error message' Theres no error messages, it just doesn't work.. His fix??? 'just go to your shared folder and launch the songs/videos from there'

Gotta love it

The Limewire player can preview and play only music files. For videos it usually chooses your default player. It somtimes happens that your default player has an codecs issue with certain file. That's why we here recommend to use the free VLC player with built-in codecs, which can play almost all media files. You can download it here and give it a try:

my default player for video and mp3 is my windows media player that works fine, just not from LW..
and it did work untill the last version

I'm in the same boat. Until the latest version, I could preview all files except .avi files. Now I'm not getting any previews, with or without the limewire player. I'm not getting the icon in the system tray either.

You can set the sys tray in your LW preferences. ie: LW's menu bar, Tools>Options>System Tray & select as you desire.

As for previewing, try resetting your default video player again. ie: Setting Default video app

well don't bother contacting tech support, because all they will tell you to do is deal with it and try double clicking on the file from the folder. I'm so happy I paid for the pro version (sarcasm)

Well, I'm fed up with the new version. Any way I can get my old version back? I tried all the tips and tricks that folks have suggested and I still can't do anything with it. Icon still won't appear, still can't preview. I'm with hdemmon, real glad I paid for another version of pro.

i am having the same problem as Trigger5150. This didnt start happening till i downloaded the latest limewire version. if anyone can help that would be greatly appreciated.

Cannot Preview or access the Help Internet Functions with 4.12.3
 

Installed the latest version 4.12.3 on 2 computers, one is Windows XP PRO and the other is Windows XP HOME. Both were able to view downloaded and downloading video files before I upgraded them to 4.12.3. Now neither will Preview or connect to the internet using links found in the Help file. Both will preview mp3 songs during download and when fully downloaded. The new version has a bug that Limewire Programmers must find and release a fix for. This is affecting a significant number of people who bought the new release.:(
