It seems there is some kind of conflict between the Java Virtual Machine and Tortoise SVN, this is the reason why FrostWire may be crashing on you lately.
We’ve found a solution by overriding some of the launch parameters. All you have to do is create a new file called launch.properties right next to your FrostWire.exe (Usually at c:\Program Files\FrostWire)
The file should contain the following, and the application will launch, and you won’t have to remove Tortoise SVN
