How to avoid " Must specify valid information for parsing in the string"

[EtaLasquera]

Since this year I got this problem randomly while my project in projects are executing thought zenno poster or project maker.

For zp poster, the project goes to bad end.
For pm I need to close and open the application.

There is a way to avoid that error?

When and where do you get this error exactly? What action at?

It occours when project in project is called.
The appearance of message is random, sometimes it appear, sometimes no.
It appear in aproximately 1/200 executions.
