Dropping it here rather than creating a new topic - Had some odd occurrences with the V12 and V13 versions of the Deep Client respectively:
1. Tried to launch V12 client through it's desktop shortcut like always (since I hadn't updated to the latest IMVU version yet). Freezes on 2% load before crashing with a stopped responding error. (The square IMVU logo popup before the login box.) Proceeds to soft-lock the entire IMVU or DC .exe.
1.1. Trying to launch the IMVU client either through the DC shortcut or the original/vanilla IMVU shortcut will technically launch the .exe but it won't actually load or do anything (appears in both taskbar and taskmanager, but doesn't actually load or proceed).
1.2. Required system restart for the IMVU/DC .exe to work again.
2. Issue persisted after updating to V13 (but not updating IMVU, as far as I can tell - figured V12 was no longer functional).
2.2. Managed to fully launch the Deep Client by opening the location folder and starting the .exe there, instead of using the shortcut generated during installation.
Putting this down as a just incase. Only issue I've ever had with the Deep Client and nothing's changed as far as I'm aware. Could be a case of broken shortcuts ..but again, nothing's changed with the V12 version, so I'm not sure. (Unless V12 stopped working when V13 was released? I know it's tied to the Mafias servers, but assumed only while the .exe is running - just like the vanilla client.)
Another weird finding is the prompt to update IMVU stopped appearing after successfully installing V13 onto the previous version of IMVU. Not sure if that's because V13 included the update files or what. Sorry if this is a little all over the place, I'm still learning exactly how the Deep Client works and such, how it interacts with updates, etc. V13 also flagged my AV, but just a false-positive due to being a very new file - to be expected.
