私が旅行中にあったことなんですけど。

私が旅行してる間に私の同僚が私のパソコンを使っていて、データを全部消しちゃったの、だから今ねメッセンジャーも使えないの。
☆my work mate was using my computer during my trip,and she have lost the all data.
thats why I cant talk on Messenger right now.

こんな感じの文でも通じますか教えて下さい。

My co-worker was using my computer during my trip, she erased all the data(files?), and I can’t even use the messenger. 　

One of my colleagues used my computer and erased all data while I was travelling, so I can’t use Messenger now. 　

While I was away, one of my colleagues used my computer and erased all the data, so now I can’t use Messenger.

While I was away is better to say because the trip is not the key subject of this statement.
