Hi, since yesterday I can’t run my sketches!  
ERROR: transport error 202: listen failed: Permission denied  
ERROR: JDWP Transport dt\_socket failed to initialize, TRANSPORT\_INIT(510)  
JDWP exit error AGENT\_ERROR\_TRANSPORT\_INIT(197): No transports initialized [debugInit.c:750]

I run Win7/64bit and BullGuard antivirus. When I switch off the Bullguard firewall, my sketch can be executed. What goes wrong? What can I do?

Apologies for not answering but I’m now also having the same problem… Sketches run only when firewall is switched off.
