Cannot share folder

[Misakvl]

When I try to share folder in linux it opens sharing windows with space for email and folder name, the "share" button is not working.

On server I get:
ERROR omq.server.AInvocationThread:82 - omq.exception.SerializerException: Deserialize -> com.stacksync.commons.requests.ShareProposalRequest; local class incompatible: stream classdesc serialVersionUID = -5985754297818659222, local class serialVersionUID = -5985754297818659212

On client:
ERROR Thread-6 AInvocationThread.run:101 - omq.exception.SerializerException: Deserialize -> com.stacksync.commons.models.CommitInfo; local class incompatible: stream classdesc serialVersionUID = -1205107021066864318, local class serialVersionUID = -1205107021066864317

I am also missing "share folder" options in windows client completely.
Any ideas?
