URGENT: Language pack Issue

[echo5]

Hello,

I am running Plesk 8.3 on my Linux host. We recently purchased a new license key and below and followed the instructions to upload it and got the below error message:

Error Message:
"The uploaded license key is not valid. The number of currently used license packs exceeds the limit defined by your license. There are 9 language packs used, your license allows installing only 1 language pack"

We ONLY use English everywhere. It was a complete surprise to me to find out there are 9 language packs used. Is there a way i an un-install ALL the language packs except English via Web UI or command line? I am literary the one-man team here, i.e very little resources limits us to form only support. Please, help.

Thanks in advance!
