I am using ABAP in Eclipse for some weeks now, but since yesterday I can't open any report or class from the back end. I only get the following message:
An error has occurred. See error log for more details.
Method getSourceFile, argument project: the argument has an illegal value: null

I have no idea, what has happened. Maybe it started after installing some Eclipse plug-ins in another Eclipse instance, but I have removed every file and every folder from my computer and installed everything again and again.
I am using Eclipse Luna SR1 4.4.1 on Windows 7 Enterprise x64
Backend: ECC 6.06 on Netweaver 7.31 SP 10
Thanks in advance,

p.s. I hope this is the correct place to ask for technical help...
