I performed a new install of windows 8 and reinstalled all apps. Sorry did not get to try your suggestion :)

tried removing just the tmpFFFF.tmp files, didn't work. Tried also removing all files in %TEMP% but that didn't work either.

I was able to resolve this issue by removing the ...\AppData\Local\Atlassian\SourceTree.exe_Url_xxxxxxxxxx... folder (actually i just moved it). Upon further diagnosis, it appears that my user.config file in the 1.2.2.0 folder was full of NULL (\0) characters (about the same size as my previous version, 1.0.8.0, only slightly larger by a few bytes). I copied my old 1.0.8.0 user.config file over top of the 1.2.2.0 user.config file and sourcetree started up properly.

Nice!!  Good call.  I've done all this Uninstall, Regedit clean, Repair, Reinstall MS .NET Framework 4, CCleaner, and all that you can imagine, and it didn't work.

Your one suggestion: Remove that damn folder "...\AppData\Local\Atlassian\SourceTree.exe_Url_xxxxxxxxxx" worked!!  Nice one Pat!

Really good call! this worked like a charm, thanks Pat

I was getting the same error, not sure if it's the same underlying exception as you though. It seems SourceTree uses the Temp folder to store files, try the following and see if it fixes your problem:

1. As you're running on Windows, open the Command Prompt and type %TEMP%
2. Navigate to that folder and remove all the files (if you find lots of tmpFFFF.tmp files then this is almost definitely your issue)
3. Once cleared try opening SourceTree again

Hope that helps

Deleting the large amount of files 65K+ in my system's %TEMP% directory fixed this error for me.
