Hi...

we never had problems like this.
We didn't change anything on the connection strategy or the host catcher.
Maybe you have problems with the old download list, which I doubt but you can try the following:
Search for 0and rename the file phex.dowload and phexdownload.xml to what ever you like.
Try to start Phex again. It should create a new fresh phexdownload.xml. But all your download will be lost. If this helps you then before you are happy take into account that all downloads are gone... sorry. If not you can restore your renamed files and the problem must be somewhere else...
