Servoy 2.2rc2

I just updated Servoy to R2 2.2rc2-build 320, repository version 25.

When I try to open the client, I get the following error:

An error occured while launching/running the application. Category: Launch File Error Could not parse launch file. Error at line 0.

It is a JNLParse Exception and the wrapped exception is java.io.EOFException: encoding.error.not.xml

When I try to open a specific solution (the full URL), I get another error, saying: Could not verify signing in resource: (http://localhost:8080/lib/j2db.jar, 1109284742593). This is a JNLPException(category: download error: java.lang.securiyException:SHA1 digest error for com/servoy/j2db/persistence/Relation.class)

Could you give me a suggestion on how to get the client started?

Thank you.
