悔過書 shuaihan

I am using computer at my work place most of time and I am not able to type Chinese at my work place, hopefully English apology can be accepted too.
I have been using CK101 for more then two years however I am not used to new version of CK101 and I made some mistake since. Please give me a chance for a new begging.

我使用CK101差不多有兩年多了,我沒有使用過新的版本,以致於犯了一些錯誤,請再給我一次機會改過,謝謝
