I'm running quicklaunch 2.15.3 on an 8320. When I go through the options menu to "check for update" I get the following:
"Error connecting to update server."
I've tried uninstalling/reinstalling (following the directions about permissions), all to no avail.
Just go re-download from wherever you purchased. Much easier.
Tried that too a couple of times. Unless you mean download new versions as they appear--which is what I'm stuck with since this function doesn't seem to work on my phone.
